This study in Germany found the average noise level in classrooms is 65 decibels.

Noise levels For satiable communication, the average speech level should exceed that of an interfering noise by 6dB lower sound noise ratios are rarely acceptable (Moore, 1997).

A loud noise in the night scared him.

Again, in your backyard, in your backyard.

To this end, the cosmological principle has been confirmed to a level of 10 5 via observations of the CMB.

So Bell employed an engineer to study those noises, to try and find out where they came from, with a view towards building the perfect hardware codec, which would get rid of them so they could think about using radio for the purposes of telephony.

A year later, I was listening to all the noise about the Middle East conflict.

This is because the shot noise of an optical communication channel is greater than the thermal noise of an electrical channel which, from information theory, means that more signal power is required to achieve the same data capacity.

Except for that creepy guy in the background.
