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
Is 92 decibels damaging to hearing?
Yes, prolonged exposure to 92 decibels can cause hearing damage. It is recommended not to be exposed to noise levels above 85 decibels for an extended period of time without ear protection to prevent hearing loss.
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?
Hearing can be negatively affected by prolonged exposure to noise levels above 85 decibels. This can lead to hearing loss over time. It is important to protect your ears from loud noise to prevent damage.
Why should you keep the volume of your music below 100 decibels?
because after a while, noise above that will gradually cause hearing loss
A noise level of 65 decibels is measured for?
A noise level of 65 decibels is considered moderately loud, comparable to the sound of a normal conversation or background music in a restaurant. Continued exposure to noise at this level can lead to hearing damage over time. It is important to protect your hearing by using ear protection in environments with sustained noise levels at or above 85 decibels.
Normal conversation is usually about decibels while noise at decibels or higher can start to damage your hearing?
65; 85
How loud is 110 decibels?
110 decibels is very loud, typically equivalent to the noise of a rock concert or a chainsaw at close range. Prolonged exposure to sounds at this level can cause hearing damage.
Which sound would have a loudness of about 100 dB decibels?
A sound approximately 100 dB decibels would be similar to the noise level of a chainsaw or a rock concert. At this level, prolonged exposure can cause hearing damage.
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 levels of noise are linked to pain or gearing loss?
Prolonged exposure to noise above 85 decibels can result in hearing loss over time. In terms of pain, noise levels above 120 decibels can be perceived as painful to the ear. It is important to protect your hearing by using earplugs or earmuffs in loud environments.
What noise level is120 decibels?
120 decibels is considered extremely loud and can cause immediate harm to hearing if exposure is prolonged. It is equivalent to the noise level of a chainsaw or a rock concert. It is important to use ear protection in environments where noise levels reach 120 decibels.
