Local laws may vary. Typicaly noise laws are to not make a lot of noise after 10 pm. You can check your city code.
You need to know the Noise Reduction Coefficient (NRC) and Sound Transmission Coefficient (STC) of the materials used.
That is the case with all amplifiers. The noise floor is always lifted when the gain is increased.
Frequency response, gain, noise, and distortion
Noise canceling headphones use neither white noise nor music. True noise canceling headphones use microphones that pick up outside sounds, amplifiers to invert those sounds, and combining circuits to combine the signal to be played with this inverted external sounds before feeding it to the speakers. The external noise vanishes by cancellation, which is why they are called "noise canceling".
Installing a noise wall along a busy highway can reduce noise pollution for nearby residents, improve quality of life, and potentially increase property values.
A noise generator produces electrical signals in both audio and video format. These are used for troubleshooting purposes in signal circuits for amplifiers and televisions.

Microwave and audio parametric amplifiers were used as low-noise amplifiers, to process low-level signals. Therefore their non-linearity probably never occurred in use. In principle, Manley-Rowe theory holds for any frequency combination, and should apply also in optics. I am not aware about the application in optics but it is clearly possible. In optical spectrum (frequencies above IR), however, quantum noise prevails above thermal noise, so low-noise amplification is usually not needed or not possible.
No. Police can pull you over for noise pollution so they tend not to make them do higher.
say, overall noise figure =f noise figure of stage1=f1 noise figure of stage2=f2 f=f1+(f2-1)/g1 f1,f2 are in linear scale(not in dB) g1=gain in stage1
To effectively reduce unwanted noise in your pedal chain, place the noise suppressor towards the end of the chain, just before the amplifier. This will help eliminate any noise picked up by the pedals before it reaches the amplifier.
