Yes, noise can amplify in sound over water due to the differences in acoustic properties between air and water. Sound travels faster and farther in water, as well as being more efficient at transmitting low-frequency noises. Additionally, the surface of the water can act as a reflective surface, causing sound to bounce and amplify.

A special device can transmit sound that is out of phase with the sound of a noisy jackhammer to the operator by means of earphones Over the noise the operator can hear your voice but you cant hear?
This device likely uses noise-canceling technology to generate sound waves that are out of phase with the jackhammer noise, effectively canceling it out. The operator can then hear your voice minus the noise, making communication clearer. However, since you don't have the earphones that are playing the out-of-phase sound, you cannot hear the canceled noise.
By what factor will the noise intensity change when sound levels increases by 8 db?
The noise intensity will double for every 3 dB increase in sound level. Therefore, an 8 dB increase in sound level will result in a little over a threefold increase in noise intensity.
How far will sound carry over water?
Sound can travel a few kilometers over water, but factors like temperature, humidity, wind speed, and obstacles in the water can affect how far it carries. In general, sound travels further and clearer over water compared to over land due to the more uniform density of water.
Does sound get louder when traveling over water?
Sound can travel faster and further over water compared to air, but it does not necessarily get louder. The sound intensity can remain the same, with the medium affecting how far the sound can travel and how well it can be heard.
How does a harmonica make a sound?
A harmonica makes a sound when air is blown or sucked through reeds that are attached to the holes on the instrument. Each reed vibrates at a specific frequency when air passes over it, producing a musical tone. The size and shape of the chambers inside the harmonica amplify and shape the sound.
What color reflects noise?
Noise over all sound frequencies is known as white noise.
What sound does a stream makes or imitates?
A stream typically makes a gentle, flowing sound as the water rushes over rocks and pebbles. It can be described as a soothing, bubbling noise that is calming to listen to.
What sound can burst your eardrum?
any noise over 120 db 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.
By what factor will the noise intensity change when sound levels increases by 8 db?
The noise intensity will double for every 3 dB increase in sound level. Therefore, an 8 dB increase in sound level will result in a little over a threefold increase in noise intensity.
What is difference between music and noice?
Noise is defined as "a sound" on google definitions. Music is defined as a group of these sounds sequenced over time to produce any idea. So music is made of noise, aka organized sound.

How do you reduce noise in a video?
this is why you see a fuzzy cover over microphones. it filters the background noise making a clearer sound. However the quality of the microphone is usually the reason why your video sound sucks. your surroundings geography has A small impact also
What are acoustic guitars used for?
An acoustic pickup is used to amplify an acoustic guitar. Instead of amplifying an acoutic guitar's sound via a microphone, an acoustic pickup can be mounted on the guitar over the soundhole to provide sound amplification.
