What are the factors that affect sound quality? What are the factors that affect sound quality

The quality of the audio source determines what quality the sound you will hear from the source, if the quality of the audio source is not high, even if you use the best front section and output, you can't hear good sound quality, the best sound source is lossless format, such as FLAC or APE, if your front section is not supported, then the *** and AAC format of 320KB S are also a good choice.

For the front-end, it mainly depends on the restoration and resolution of the sound source by the machine itself, because the **file exists in digital form, and you can only hear the digital conversion into the analog real sound you hear through the output medium, then the conversion from digital to analog is also crucial, and a good front-end restoration and resolution can allow you to hear the highest sound quality that can be provided by the closest audio source (that is, the sound closest to the pronunciation object before recording into a **file).

For the output medium, this thing goes without saying, if the sound of the front-end output is constant, then the output medium determines whether you can hear the true quality of the front-end output signal.

Let's talk about the two concepts that most people are easy to confuse now, that is, "sound quality" and "sound effect", sound quality is the quality of the sound, that is, whether the sound you hear is closest to the sound made by the real object, for example, whether the sound you listen to someone singing is close to the sound of this person actually singing in front of you, or whether the sound of you listening to a violin with *** is close to the sound of a person holding a real violin playing in front of you, this is "sound quality". The "sound effect" refers to the additional effect of the front end or headphones on a certain sound that has been determined by the "sound quality", which is the so-called super bass or something, which is to strengthen or weaken a certain aspect of the real sound to change your "listening sense". The mistake that ordinary people tend to make is to always ask what ** device and headphones have good "sound quality", but in fact, the concept in mind is just sound effect.

The above are all typed word by word, I hope it can help you, hope.

The characteristics of a sound can be described by three elements, namely loudness, pitch, and timbre.

1. Loudness: The subjective perception of the human ear about the strength of the sound is called loudness. Loudness is related to the amplitude of the sonic vibration.

2. Tone: The human ear's perception of the height of the sound is called blind Zheng tone, and the tone is mainly related to the frequency of sound waves.

3. Timbre: Timbre is the reason why people distinguish two voices with the same loudness and the same tone is the comprehensive response of the human ear to sound waves of various frequencies and intensities, and the timbre is related to the vibration waveform of sound waves and the spectral structure of sound.

The factors that affect the timbre are:

Timbre is determined by factors such as the material, structure, and vibration pattern of the embody.

The timbre depends on the emitter itself, and the timbre of the Lu sound is different depending on the vibration of the emitter. Timbre is the basis for us to distinguish various sounds, not affected by pitch and loudness, even if different instruments produce the same tone and loudness, we can distinguish them, this is due to the difference in timbre.

Timbre refers to the sound quality of an instrument or voice, this is **timbre, marked as an instrument or voice, and there should be nothing wrong with vocals or instrumental music. Timbre is divided into music and noise.

The concept of timbre:

Timbre refers to the frequency performance of different sounds, which always have different characteristics in terms of waveform. Different objects vibrate differently, just as the leaves of a tree vary from one tree to another.

Different speech bodies are made of different materials and structures, and the timbre of the sounds produced is also different, for example, the piano and violin are different from the human voice: everyone's voice will be different.

Timbre is also known as fret. Why is the tone different? Different overtones can always be combined to form different sounds.

Each musical instrument, different human vocal cords, and all other vibrating objects can produce different sounds, and these sounds can also be displayed by instruments to display waveforms.

1. The first place in sound quality is determined by the quality of the speaker, and the second place is the sound source and power amplifier. If the speaker is HIFI high quality (**5000 yuan), with an ordinary 2000 yuan power amplifier (Bluetooth as the sound source), it is HIFI sound quality! If the speaker is of ordinary quality (1000 yuan), with a high-level power amplifier of 8000 yuan (Bluetooth), it is ordinary sound quality.

2. The role of the wire rod is relatively small. Ordinary fever wire for tens of dollars and high-grade wire for thousands of dollars, the difference is almost inaudible!

3, CD player sound quality is the best, high quality *** can also be used, if the speaker is good, the difference is very small, *** is just more than 15kHz treble is missing (over 30 years old ears can not hear the frequency above 15kHz, and the frequency of musical instruments are below 15kHz).

4, "lossless**" is a non-existent drop, it is a rookie drop that does not understand **! All ** have losses, CD losses are minimal, and they are not "lossless sound quality"!
