How do you measure noise on your phone? Is cell phone noise detection software accurate?

1 6 Step by Step Reading.

This software has no plugins, no ads, and is small enough to install with confidence.

After the installation, the icon of the software on the phone is:

As long as you open the app and allow it to use your phone's recording function, you can start the detection right away.

If the family is watching TV in the room, then in your bedroom, it is generally about 20 to 30 decibels.

The earpiece of the mobile phone is very sensitive.

If there is someone talking next to you, then the noise is more considerable, and it suddenly rises to about 50 decibels.

If it's a little louder, here's what happens. Can you still live with it?

In those days, blowing into a mobile phone microphone was similar to the effect of a train transit.

But think about it, when you sleep, do you allow others to whistle in your ear?

Precautions. As long as the smartphone is not faulty, then its earpiece is still very sensitive and can be used to detect ambient noise.

The software used to measure the sound decibel of the mobile phone is called the sound meter, and the specific way to test the sound decibel is as follows:

5. In the interface that opens later, you can automatically see the decibel number of the current sound.

Mobile phone software testing is inaccurate data.

1. The amplitude is not accurate, and the microphone used in the laboratory needs to be strictly calibrated, simply put, the conversion rate of the sound wave being converted into an electrical signal needs to be confirmed by the standard sound.

2. The frequency response characteristics are not accurate, the sound of different frequencies is collected by the mobile phone microphone and there are different attenuation characteristics, the attenuation characteristics of the laboratory microphone are tested and loaded into the test equipment, the frequency response characteristics of each mobile phone microphone are definitely different, and the same test software must not be distinguishable.

The noise test software of the mobile phone can be used as a qualitative comparison, in simple terms, two sound sizes can be compared; It is also possible to determine the frequency component of the sound source, i.e. which frequencies are mainly contained in the sound (frequency is a concept relative to time, which is processed very accurately by the mobile phone processor).

The software used to measure the sound decibel of the mobile phone is called the sound meter, and the specific way to test the sound decibel is like the dust rolling socks:

Tools: Huawei P30, HarmonyOS version.

5. In the interface that opens later, you can automatically see the decibel number of the current sound.

Summary. Hello, there is not much difference between the noise decibels measured by the mobile phone and the actual one. Generally speaking, there may be a certain gap between the accuracy of mobile phones in measuring noise decibel levels compared with professional noise testers, but this gap is not very large.

Mobile phones typically use a microphone to detect noise and then convert the detected sound to a decibel level. The microphone sensitivity and frequency response of a mobile phone are important factors that affect the accuracy of the measurement, and in general, the microphone performance of high-end phones will be better than that of low-end phones, so the noise measurement accuracy will also be higher. However, it is important to note that the measurement results of noise decibel levels are greatly affected by the environment and measurement conditions.

In different environments, the noise decibel level measured by the same mobile phone may vary. Therefore, when making noise measurements, it is necessary to ensure the consistency of measurement conditions, such as measurement location, ambient noise level, etc., to ensure the accuracy of measurement results. At the same time, when there is a large gap between the measurement results and the actual situation, you can also refer to the measurement results of other professional noise testers for comparison to better understand the actual noise level.

You're on it, I need to be real and effective.

Ordinary mobile phone applications usually have a certain error in measuring noise decibels, and there is a certain gap between them and the actual noise level. This is because the mobile device's built-in microphone and preset algorithms have limited accuracy and can be affected by the external environment, such as wind, water, and other noises. Therefore, using a mobile phone to measure noise decibels alone cannot get accurate results, and it needs to be measured in combination with other noise testing instruments, such as sound level meters and other professional instruments.

It could be more or less. The decibel value of mobile phone testing is a very common and type estimation method, while professional testing will use more accurate instruments and standards for testing, so the actual results will be more accurate. However, if the methods and tools of mobile phone detection are used correctly, the estimated results are usually very close to the results of professional sensitivity testing.

The tester then measures according to the prompts. Open the software and test the result in the office was 59 decibels. The result of the test in the subway is 79 decibels. The measured result on a factory floor is 82 decibels.

2. Measure ambient noise with your phone. Decibel tester app.

Use your phone's microphone to measure the volume decibel (dB) of the noise and display a reference. The actual sound level of many of our Android devices is measured in decibel (A). High decibel levels can jeopardize your physical and mental health and hearing function.

It is best to avoid exposure to noisy environments when measuring.

**A decibel tester and then measure according to the prompts. Open the software and test the result in the office was 59 decibels. The result of the test in the subway is 79 decibels. The measured result on a factory floor is 82 decibels.

The level of noise: People use decibels to express the level of sound intensity. 30 to 40 decibels is an ideal quiet environment, in order to protect hearing, the sound should not exceed 90 decibels, in order to ensure that the sound of work and study should not exceed 70 decibels, in order to ensure rest and sleep, the sound should not exceed 50 decibels.

Basic Approach to Noise Control:

In order to prevent noise, Professor Ma Dayou, a famous acoustician in China, has summarized and studied the hazards and standards of various types of noise at home and abroad.

In order to protect people's hearing and physical health, the permissible value of noise is 75 to 90 decibels.

To ensure conversation and communication, the permissible value of ambient noise is 45 to 60 decibels.

For sleep time is recommended at 35-50 decibels.

Brand model: Huawei P50

System: HarmonyOS 3

Software Version: <

Mobile phones can measure noise decibels. Take Huawei P50 as an example, in the application market** a decibel tester app, as long as you open this software, and allow the software to use the recording function of the mobile phone, you can start testing immediately. If the family is watching TV in the room, then in the bedroom, it is generally about 20 to 30 decibels.

The earpiece of the mobile phone is very sensitive.

Decibel tester applicable scenarios:

1. Use in the community and bedroom to judge whether the current environment is noisy and whether it is conducive to sleep;

2. In schools and offices, check whether there is excessive noise around the office area and whether the office environment is qualified;

3. In public places such as squares, noise dyeing is one of the most influential environmental dyeings, and higher decibel noise can even cause serious damage to people's eardrums.

The decibel meter is also called a sound level meter and a noise meter. When converting the acoustic signal into an electrical signal, it can simulate the temporal characteristics of the response speed of the human ear to the sound wave; Frequency characteristics with different sensitivities to high and low frequencies and intensity characteristics with varying frequency characteristics at different loudnesses. Therefore, a sound level meter is a subjective electronic instrument.
