Why would a rabbit with sharp hearing be more likely to survive than one with less keen hearing?
A rabbit with sharper hearing can hear more clearly and take in more information for its surrounding environment. If a nearby predator makes a soft noise before attack, hearing that noise is the difference between life and death for the rabbit, so sharp hearing is critical.
What is the decibel of a chainsaw?
The sound pressure level in decibels depends on the distance to the chainsaw. In 1 m distance we can get 110 dB. In 10 meters distance we get 90 dB. So keep off the noise maker.
What is friis equation?
Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation. Fn = F1 + (F2 - 1 / G1) + (F3 - 1 / G1G2) + (F4 - 1 / G1G2G3) ....... and so on Where: Fn = The total noise of all stages together F1 = The noise factor of stage 1 F2 = The noise factor of stage 2 F3 = The noise factor of stage 3 G = Gain of respective stage Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation.

What other words mean no noise?
Silence, quiet, peaceful.
What is ratio of 6 party hats and 4 noise makers?
6/4
What is the level of noise that affect hearing?
85 decibels.
How many decibels make up noise?
It depends on what organism is hearing the noise. For us humans, that would be 0 decibels.
At what noise level is your hearing negatively affected?
85 decibels
Why should you keep the volume of your music below 100 decibels?
because after a while, noise above that will gradually cause hearing loss
Normal conversation is usually about decibels while noise at decibels or higher can start to damage your hearing?
65; 85
A noise level of 65 decibels is measured for?
A noise level that measures 65 decibels is for a normal conversation on the noise scale. On this scale, 0 decibel is the threshold of hearing and 140 decibels is a jet plane at a distance of about 50 meters away.
What effect does noise pollution have on hearing?
Noise pollution, such as jack hammers or constant tapping, can cause stress, headaches, impair hearing, and disturb every day life. Human ears have the capability to withstand noise upto some decibels beyond which it qwill damage the ear
What are the effects of noise pollution to humans?
Noise pollution, such as jack hammers or constant tapping, can cause stress, headaches, impair hearing, and disturb every day life. Human ears have the capability to withstand noise upto some decibels beyond which it qwill damage the ear
What levels of noise are linked to pain or gearing loss?
Anything above 115 decibels is considered to be in the "pain/hearing loss" area.
Why do people wear ear muffs?
People should wear a hearing protector if the noise or sound level at the workplace exceeds 85 decibels (A-weighted) or dBA. Hearing protectors reduce the noise exposure level and the risk of hearing loss. If hearing protection is required, then a complete hearing conservation program should be implemented.
What other sounds are harmful to your ears?
Any sound which is over 80 decibels and continual will damage a persons hearing, any sound above 89 decibels and ear protect must be worn if the noise is continual or permanent deafness becomes a high risk - regardless of where or from what the sound comes from. 100 decibels is about the noise of a plan leave.
Can your own screaming damage your ears?
Yes, if you can produce more than 85dB of noise. The louder the scream above this threshold, the faster you can damage your hearing. At 100dB, it takes about 20min. Normally it is unlikely unless you scream a lot. Opera singers sometimes have hearing damage due to the loudness and time extent of their singing.
