What is the loudest sound a human can hear?
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
Does the blue whale make a louder sound than a polar bear?
Yes it does, it has alouder soud by around 45 Db
Do harmonicas hurt dogs' ears?
Aside: A similar question is often asked by folks when I practice my bagpipe chanter. I suspect it is a question of taste on their part and skill on my part without any true consideration of the dog's otic healthAnswer:A dog's ears hear essentially the same as we do with a better registering of higher end frequencies (in excess of 20K Hz) We call these frequencies "ultrasonic"Pain from sound is caused by air pressure from the pain (loudness). Noise levels of 85 db can cause hearing loss over time. Noise levels of 140 db can cause pain.A harmonica at its loudest is not in the painful range to the player (the closest set of ears) although it may be detrimental over the years. Sound levels fall off with every doubling of the distance, so at a dog's ear level the sound will be much reduced from that reported by the player's ears.As a test - consider that dogs can bark loud enough to hurt our ears Dogs ears are closer to the bark than our ears and the sound from their point of veiw is much louder. Barking does not harm a dogs ears.
Does loud music hurt baby bunnies ears?
Rabbits grunt and make rasping noises when they are sexually aroused and want to mate. They can also squeal if they are in extreme pain, extremely frightened, or furiously angry when fighting, as a means of scaring their opponent. Most of the time though, they just snuffle and sniff- many rabbits go their whole lives without needing to use their voices!!
How many Hz is a dog bark?
200 to 9000hz
How loud is 60 db?
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
What is the sound level of the noise measured at 42 dB?
The sound level of the noise measured at 42 dB is considered moderate and is similar to the noise level of a quiet library.
What is the relationship between sound pressure level and the perception of sound in a dB scale?
The relationship between sound pressure level and the perception of sound in a dB scale is that as sound pressure level increases, the perception of sound also increases. The dB scale is a logarithmic scale that measures the intensity of sound, with each 10 dB increase representing a tenfold increase in sound intensity. This means that small changes in sound pressure level can result in significant changes in the perception of sound.
What is the difference between dB HL and dB SPL?
dB HL stands for decibel Hearing Level, and dB SPL stands for decibel Sound Pressure Level.
What is -10 dB?
-10 dB represents a sound level that is 10 decibels lower than a reference level. It corresponds to a sound intensity that is one-tenth of the reference level.
What is an example of a sound level measurement that is considered to be 55 dB?
An example of a sound level measurement that is considered to be 55 dB is a normal conversation at a close distance.
If one lawn mower causes an 80 dB sound level at a nearby point what sound level at that point would four lawnmowers together cause?
When four lawnmowers are together, the sound level they produce would be around 86 dB. This is due to the way sound levels add up - each additional lawnmower increases the overall sound level by about 3 dB.
What is the intensity of sound at 121 dB?
The intensity of sound at 121 dB is approximately 10^9 W/m^2. Sound intensity is measured using the formula I = 10^(dB/10), where dB is the decibel level.
What is the sound level of 42 dB and how loud is it?
A sound level of 42 dB is considered to be relatively quiet, similar to a quiet library or a soft conversation. It is a low level of noise that is not very loud.
What is the unit of measurement for sound pressure level?
The unit of measurement for sound pressure level is decibels (dB).
Will two separate 50db sounds togather constitute 100 db sound?
No, when two sounds of the same level (in this case 50 dB) are played together, the resulting sound level will be 53 dB, not 100 dB. The decibel scale is logarithmic, so sound levels do not add up directly.
What the db for a clap when mixing?
In mixing, a dB (decibel) for a clap sound is typically around -6 dB to -3 dB. This level ensures that the clap sound is audible and sits well in the mix without overpowering other elements. Adjust the level based on the overall mix and the desired impact of the clap sound.
