A song, played with the same equipment, a large volume can indeed restore more details.
The quality of the recording and the ability to play back the system will affect the reproduction of the details of the music. However, the same equipment, the louder the greater the ability to restore details? This not only involves the playback capability of the equipment, but also the receiving ability of the human ear.
Explain as follows:
There is a very important experiment in the history of human ability to perceive sound. The result of this experiment is called the Equal-loudness Contour. In 1933, two researchers at Bell Labs, Harvey Fletcher and WA Munson, pioneered such experiments, and have since been repeatedly tested and confirmed by others. In 2003, the International Organization for Standardization (ISO) published the ISO 226:2003 standard in conjunction with the results of various experiments in history.
The figure below is a standard diagram of the ISO 226:2003 equal curve.
figure 1
figure 2
Figure 1 The vertical axis on the left represents the sound pressure level (SPL) and the horizontal axis represents the sound frequency. The red line in the figure is the Phon value curve (Phon is the unit of loudness Loudness), and the number marked above each red line is the Phon value of this curve. Figure 2 reverses the vertical axis of Figure 1.
As shown in Fig. 1, for the human ear, a 1 kHz sound, at a sound pressure level of 20 dBSPL, achieves a loudness of 20 Phon. And a 100Hz sound wants to achieve the same loudness, and its sound pressure level needs to reach 50dBSPL [3].
From the two figures, the following conclusions can be drawn:
Humans are most sensitive to IF signals. At different sound pressure levels, the IF signal is generally better perceived.
Human perception of low frequency and high frequency signals is greatly affected by sound pressure levels.
The louder the louder, the more straight we perceive the signal frequency, that is, the louder the louder, the easier it is for our ears to sense the low and high frequencies of the signal.
In music, low frequencies give people a sense of strength, while high frequencies are associated with brightness, clarity, and airiness. Therefore, the louder the louder, of course, the richer the details of the music.
As mentioned above, under the same audio and playback devices, increasing the volume does make people feel more sound details.
