Is velocity of sound is maximum in water?
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. In diamond the speed of sound is fastest. It is c = 12000 m/s.
What the smallest amount of sound is that can be heard?
Zero dB is the quietest sound that may be heard by the average of a group of young men who have not been noise exposed. By definition, one half of these will be able to hear a quieter sound, and the other half will be less sensitive. Nowadays, these limits are more precisely defined in terms of physical units. Some animals hear at a different sensitivity to us, and over a different frequency range.
What color reflects noise?

What sound can burst your eardrum?

What are some advantages of noise cancelling headsets over noise isolating earbuds?
Noise cancelling headphones uses a microphone near to the ear to generate and anti noise which is then mixed with the main sound. This anti noise cancels out the noise by using the phenomenon of destructive interference. Therefore, the final sound from a noise cancelling headphone is crisper in comparison to its counterpart the noise isolating earbuds which try to block the noises by using some sort of cushions.

How far do wolves howl?
A howl is a noise. There is no way to choose how far a noise will travel. Wolves will howl as they see fit, then the noise will carry as far as it can. Longer over water. Longer downwind, shorter upwind. Longer over open ground than through forest. If the wind picks up, the sound of the howl soon drowns in the general rustle and noises of the wind.
