What is the decibel level of an average rooster's crow?
An average rooster's crow is approximately 90 decibels. This is about as loud as a dog barking. Chickens themselves average 60-70 decibels, which is on par with human conversation.

Thanks for the feedback!
120 dB is about the maximum.
Any decibel level above 85 is dangerous
180 dB is a result from the barrett M107A1 50 cal long rifle.
Fire engine is 120 Decibels which is also the threshold of pain.
On average, about 120 db, depending on size.
147dB Based on Formula 1 race car full throttle drive bye
Between 1 and 20db
It is important to understand that a decibel is just a unit of measure that is used to determine loudness of a sound or amount of hearing loss. Normal hearing is found betwe…en 0 and 25 dB in adults. For children, 0 - 20dB. Mild hearing loss is found between 26 - 40 dB in adults. For children, 21 - 40dB. Moderate loss if found between 41 - 55 dB in both. Moderately severe if found between 56-70 dB in both. Severe if found between 71 - 90 dB in both Profound if found 90 dB or greater in both
If I say: Level of a helicopter = 130 dB, most people are content. Laymen think that a specific decibel value belongs to a noise source. Like heavy truck = 100 dB, jackhamme…r = 110 dB, rock band 120 dB. That is not correct. Alway is forgotten that the distance from the sound source to the measuring point plays an important role. Sound level decreases by (−)6 dB per doubling of distance from the source. Without any distance a dB value is really nonsense.
Human speech measured in 1 meter distance is arround 60 dBSPL. In 2 meters distance it is 6 dB less, that means 54 dB. Never forget tu tell the distance. The closer …you are to a sound source the louder it is.
For your ears a level below 85 dBSPL is safe. 0 dBSPL = 20 µPa.
An Average teen girl's yelling is upto 105 Decibels. Humans can not bear more then 125 decibels.
For many vehicles, the road contact noise will be larger than the noise from engine or exhaust. Even inside the vehicle, the noise level will vary from 70db or so for a nois…y car, down to 40dB for a quality car. Outside the car, the sound level should not be greater than 80 dB at say 3m. It varies widely with type of engine, type of car, and speed.
Legal limits will surely vary from one jurisdiction (country, or state) to another. They may also vary from time to time, in the same jurisdiction. It will also depend on the …circumstances. For example, if you make a certain amount of noise in your house, and disturb the neighbors, they might be entitled to complain. On the other hand, an airplane taking off makes much more noise than that, and that might be perfectly legal.
A crowing rooster can have a crow that is upwards of a decibel level of 70. This can be comparable to the decimal level of a raised human voice.
