A change of 1 dB in sound level is barely perceptible to a listener, while 2 db is readily perceptible. An attenuation of 3dB corresponds to cutting power in half, while a gain of 3 db corresponds to a doubling of the power level. A gain of -3 dB is the same as an attenuation of +3 dB, corresponding to half the original power level.

2. Optical. Optical compressors affect the dynamics of an audio signal via a light element and an optical cell. As the amplitude of an audio signal increases, the light element emits more light, which causes the optical cell to attenuate the amplitude of the output signal.
Audio input, why need gain and attenuation? | Electronics ...

I have a audio sink ( it is chip's audio input ), there are gain and attenuation settings. My audio source is constant level, so, I think I only need gain or only need attenuation for this sink, am I right ? What I am confusing is I saw a setting both have gain and attenuation.... I feel it is strange, is the setting is correct ? could you please

Figure 1. Logarithmic response of the potentiometer to changes in sound pressure levels. In general, the midpoint of the rotation usually gives around 20dB attenuation of the audio signal, with attenuation rapidly increasing from the midpoint counter-clock wise (CCW). There is finer control over the "louder" settings from the midpoint clock wise (CW).
