Locate and voltage regulators which are used by the audio circuitry near to rectifiers / PSU input and connect with their own connections also. Signals Where possible avoid in and out audio signals to and from IC's running in parallel on the PCB as this can cause oscillations which feed from output back to input.

In the context of audio, the decibel is defined as follows: dB = 10 log 10 (I/I 0) where I = the measured intensity (W/m 2) I 0 = 10 -12 W/m 2, which represents the lowest sound intensity detectable by the human ear The figure below shows a variety of sounds and their dB intensity measurement. Examples of sounds and their intensity (in dB).
