**: Why use two ears to listen?

Ask the question: "Why do you want to hear with two ears?" ”

Make assumptions:1Hearing with two ears is louder than the volume collected in one ear, so you can hear it more clearly.

2.Listening with both ears may be related to discerning the direction of the sound source;

3.The left ear listens to the left voice, and the right ear listens to the right voice;

4.It may be that if you listen with one ear, this ear gets tired quickly, so share the fatigue with both ears.

5.The sound has a three-dimensional effect.

Purpose 1: Verify that listening with two ears is louder than the volume collected in one ear, so it can be heard more clearly.

Protocol: 1) Plug one ear with cotton and then test the hearing distance of the other ear (first approach a ticking alarm clock, then walk backwards until you can't hear it, and then make a mark). (2) Try again, listen with both ears at this time, and note the distance where you can't hear the alarm sound.

3) Do a few more experiments and compare the experimental results, if you listen far away with two ears, it means that the volume collected by both ears is greater and you can hear more clearly. (Ma Rong).

Objective 2: To verify that listening with two ears may be related to discerning the direction of the sound source;

Protocol: 1) One person stands still with their eyes closed, and the other person stands silently in front of the person with their eyes closed, behind, to the left, and to the right at the same distance, holding a clock or watch in their hands. When reaching the front and back of the person who closes his eyes, let the "ticking" sound of the bell come out** When changing the location, be sure to cover the bell and not make a sound), let the person with the closed eyes judge the position of the sound source with both ears.

2) Cover the left ear to make the position of the sound source change irregularly, repeat the above experimental process, and judge with the right ear; Cover the right ear to make the position of the sound source change irregularly, repeat the above experimental process, and judge with the left ear. The results of the judgment of one and both ears in each different position were recorded and compared. If the experimental results are different, it is proved that binaural hearing is related to judging the position of the sound source, otherwise it is irrelevant.

Wan Mengyu) Purpose 3: Verify that the left ear listens to the left sound and the right ear listens to the right sound;

Experimental scheme: 1) Turn on the radio first, then turn the right ear in the direction of the radio, block the right ear, let the left ear listen, if the left ear can hear the sound of the radio, it proves that the left ear is wrong to listen to the left sound. If no sound can be heard, the assumption is valid.

Cai Xinying) (2) asked the experimenter's left ear to face the direction of the radio, blocked the left ear, and listened with the right ear, and performed the same experiment. If the sound of the radio can be heard in the right ear, it proves that the right ear is wrong to hear the right voice. If no sound can be heard, the assumption is valid.

By listening to the sound with both ears, you can determine the location of the sound source.

Hearing with both ears can determine the location of the sound source.

It's like seeing things with two eyes.

If you look at things with one eye, you can't accurately judge the location of things.

Try it if you don't believe it.

One ear can't hear accurately!

Two ears can create a binaural effect.

Is it OK to listen with one ear?

First of all, our ears have a positioning function, and if we only listen with one ear, we will not be able to locate it correctly, and we will hear the sound in any direction.

Secondly, relying on one ear for a long time to listen will gradually worsen the hearing loss of the worse ear, resulting in hearing deprivation and worsening hearing problems.

Thirdly, in a noisy environment, because of the inability to locate correctly, it will lead to the inability to hear the target language when multiple people are talking, and the recognition rate will decrease.

1. In a very noisy environment, both ears can understand the content of the speaker's speech;

The loudness of the sound can be increased, and even smaller sounds can be heard.

In addition, binaural listening and mono listening is the difference between stereo and mono, when listening in both ears, it will be more three-dimensional and enjoy the surround sound effect;

2. It can make it easier for us to identify the direction of the sound, whether it is waiting for the elevator, which side of the elevator comes first, which direction the car is coming from, and which student is speaking during the group discussion, we can easily distinguish it;

3. We can choose a place to sit during meals, rides, and group discussions, and we don't have to listen intently, and we don't have to worry about the sound coming from one side of the head being attenuated by the head when it bypasses the head; No more worrying about missing out on important information.

4. The sound on both sides can be easily heard, which can improve the fatigue of monocular listening, and the more voices heard, the patient's speech time will be shortened, and the patient will integrate into society as soon as possible.

Hello, 1. Eliminating the cephalo effect refers to the difference in the intensity of the sound heard by the left ear and the right ear due to the different positions of the sound source. For example, if a sound comes from the left, the left ear will hear a louder sound than the right ear. It is caused by the barrier and attenuation of the head and can cause hearing loss of up to 6 8dB.

If the hearing loss in the hearing loss is not close in the ear, the hearing loss is directed toward the source of the sound when the sound comes from the worse ear. 2. Distinguish the direction and positioning of the sound sourceWhen the sound comes from different directions, the length of time it takes for them to reach both ears and the intensity of the sound will be slightly different, and the brain can judge the sound source according to the length of time and the intensity of the volume. If you listen with one ear, it is difficult to ensure that you can accurately find the direction of the sound source through the sound.

3. Improve the speech recognition rateBinaural listening can reduce noise through the integration of the central nervous system to obtain a better signal-to-noise ratio. This means that you can hear better, hear more clearly, hear more comfortably, hear more three-dimensionally, and have a deeper short-term auditory memory, especially in noisy environments. In addition, binaural listening also increases the sound gain (about 5dB), which means that the sound heard feels louder.

4. Avoid hearing deprivation Hearing in one ear for a long time will cause a phenomenon, that is, the ear that is used less will have disuse sexual dysfunction or loss of function, which is the so-called hearing deprivation phenomenon.

To put it simply, the two ears work together to collect the sounds around them, and the brain integrates the sounds on both sides, removing unwanted noises and selecting the important sounds you want to hear, which is binaural listening.

Zhang Ailing's words are that you are more focused.

Because it's a basic respect for other people, so that you can communicate better.

Top 10 Benefits of Wearing Hearing Aids in Both Ears:

1. Improve the ability to locate sound sources.

2. Improve noise reduction and speech comprehension.

The pinna of the human ear has the function of sound collection and noise reduction. It is very important for a patient with hearing impairment to improve the signal-to-noise ratio. Wearing both ears means that both ears have the ability to collect sound and reduce noise, which is of great significance for improving speech discrimination.

3. Enhance the integration effect of binaural loudness.

The loudness of sound received by binaural hearing is somewhat higher than that of a single ear, which is about 3 dB better than the single ear threshold at the threshold level. At the suprathreshold level, the binaural threshold is about 10 dB better than the single-ear threshold.

4. Avoid late-onset hearing deprivation effects.

5. Delay the decline of auditory nerve function.

To address the phenomenon of auditory deprivation is to address the progressive decline of auditory central nervous system function.

6. Improve listening comfort and participate in multi-person conversations.

Due to the optional hearing aids in both ears, it improves the ear's own sound collection, noise reduction, gain, positioning, balance function and fusion effect, and the user will greatly improve the signal-to-noise ratio and excellent listening comfort of the sound signal heard.

7. Eliminate the cephalo effect.

If a patient has asymmetrical hearing loss in both ears, when the sound comes from the direction of the hearing loss ear, the hearing ear with better hearing will be directed towards the sound source, which is known as the cephalous effect.

8. Inhibit (mask) tinnitus.

The amplified sound of hearing aids can suppress the sensation of tinnitus. Therefore, in order to improve the comfort and intelligibility of hearing, deaf patients with tinnitus or encephalita in both ears should try to choose binaural matching, which can not only improve hearing, improve hearing effect, but also feel that the tinnitus is eliminated.

9. Prevent unilateral auditory fatigue.

Binaural wearing can improve the integration effect, noise reduction and orientation ability, and will provide the ears with relatively high comfort and signal-to-noise ratio, which will avoid frequent unilateral volume increase and prevent hearing fatigue.

10. Reduce the effect of ear occlusion.

Ear occlusion is a subjective sensation of a significant increase in the loudness of low-frequency sensations generated by oneself (e.g., talking, chewing, swallowing, walking, etc.).

Therefore, as long as there is hearing impairment in both ears, and on the premise of confirming that there are no other contraindications to fitting, it is necessary to choose binaural fitting as much as possible. Let our patients realize: 1. It is better to wear hearing aids than not to wear hearing aids; 2. It is better to wear it early than late; 3. The overall effect of wearing both ears must be better than wearing one ear.

First of all, it's definitely a matter of personal habits, watching the singers on the stage, with the left and right.

The left brain has the function of language and is good at logical reasoning, mainly storing information and knowledge obtained after birth.

The five senses of the right brain are hidden at the bottom of the right brain, which can be called the five senses of instinct, which control the autonomic nervous system and the resonance of cosmic fluctuations, etc., and are related to the subconscious. The right brain processes the received information in an instant, so it can process a large amount of information at the same time (mental arithmetic, speed reading, etc. are the expression of information processing by the right brain). The five senses of the right brain are controlled and suppressed by the rationality of the left brain, so it is difficult to exert the underlying instincts.

However, if you know how to use your right brain, you can distinguish colors by listening to sounds, or by appearing images or smelling smells. Psychologists call this condition empathesia, and that's the potential of the right brain.

You can see that the right brain is better suited to deal with the five senses. The human brain controls the human body intersecting, so theoretically speaking, it is better to have the left ear.

This experiment illustrates the properties of the propagation of sound waves by matter, and the propagation characteristics vary depending on the material.

Composition of the ear. The ear consists of three parts: the outer ear, the middle ear, and the inner ear. Auditory receptors and positional receptors are located in the inner ear, so the ear is also called a auditory. The outer and middle ears are also listed as appendages to hearing bits.

The outer ear consists of two parts: the auricular and the external auditory canal. In addition, there are ear hairs and some glands on the ** of the external auditory canal, and the secretions and ear hairs of the glands have a certain blocking effect on the entry of foreign bodies such as dust from the outside.

There is a large hole on the outside of the ear, called the external ear gate, which connects with the external auditory canal. The auricles are funnel-shaped and have the effect of collecting foreign sound waves. Most of it is scaffold by elastic cartilage located under the skin, and the small part below contains only connective tissue and fat under the skin, which is called the earlobe.

In clinical application, the earlobe is the site of auricular acupoint and auricular acupuncture anesthesia, and the earlobe is also often used as the site of clinical blood collection.

External auditory canalThe external auditory canal is a curved tube from the external auricular hilum to the tympanic membrane, about cm long, and its ** continues from the pinna. The outer third of the wall of the external auditory canal is made up of cartilage, and the inner two-thirds of the wall of the external auditory canal is made of bone. The cartilage part has ear hair, sebaceous glands, and cerumen glands.

Because this is what man has formed in the process of continuous evolution. It's a natural phenomenon.

If one ear listens to sounds, it is certainly not as accurate and clear as two ears, and it will be very convenient to face the direction of this ear, while the other side will feel quite inconvenient, just like the eyes, although one eye can see, but it is not as far as two eyes to see the same reason.

This is because having two ears makes people appear more coordinated, and the two ears are able to hear more fully and distinguish different positions based on sound. In addition, the direction and angle of the departure sound can be judged by both ears.

This is to be able to better hear the sound in all directions, if people only have one ear, then they will not hear clearly, which is equivalent to wearing only one earphone, which is too uncomfortable.

Because one ear hears the sound more subtly, while the two ears hear more carefully and more comprehensively.

It may be to keep people's facial features look relatively coordinated, and on the other hand, it is produced to coordinate some functions of the human body.

I think it's because people need to hear more and feel more, so I gave two ears and don't ignore the importance of listening.

I think it's to hear the sound more evenly, if you only have one ear, whether it's the left ear or the right ear, the other side can't hear clearly.

This allows you to hear more clearly. It can reduce the pressure on one ear. Even better.

Hello, why listen binaurally?

There are many benefits of binaural listening: 1. Avoid hearing deprivation, protect residual hearing and recognition ability in both ears. 2. The superposition of sound, binaural listening can increase the compensation of 5 decibels, and you can hear more clearly.

3. Sound source localization, 4. Noise suppression, 5. Reduce head shadow effect. 6. Auditory fusion. Hope mine is helpful to you.

Hello! Our ears are balanced and symmetrical on both sides of the skull, and while listening to sound, both ears can produce a sense of auditory direction, three-dimensionality, which is conducive to auditory orientation and positioning. In a noisy environment, the loudness and clarity of the sound in one ear are not as loud as in both ears.

Hope mine is helpful to you.
