I was sent this by a friend today....

"The sound of a rooster crowing can reach 142 decibels (when measured at the rooster’s head). To put that in context, a chainsaw produces about 120 db and a jet taking off 25 metres away is about 150 db and can lead to eardrum rupture. Scientists in Belgium questioned how could a rooster crow so loudly and not damage its own hearing.

They discovered that when a rooster opens his mouth fully to crow, the auditory canal (the pathway from the outer to inner ear) is shut off. This means that while a rooster is crowing, he can’t hear anything. In contrast when a hen opens her beak completely, there is only a slight closure of her auditory canal. What scientists haven’t explained is how nearby hens can tolerate the loud noise."

Not sure if it is true or not but it would explain why cockerels have no care about crowing all day!!!!

The sound of a rooster crowing can reach 142 decibels
:eek: Wow, I had to Google that. Depending on the article, I see average rooster crows anywhere from 70 db to 130 db. So I guess it is possible for a rooster to get as loud as 142 db. I guess it's easy to see why many communities ban roosters from the backyard flock in town with close neighbors.

FYI, here's a nice little chart on average sounds in our environment.

Noises that Cause Pain and Possible Permanent Damage to the Ears
Above 140 decibels - gun going off, fireworks, rocket launch, aircraft carrier
130 - average rooster crowing, jet engine

Noises with the Ability to Cause Temporary Hearing Loss
120 decibels - police siren, thunder, chain saw
110 - rock concert
100 - helicopters, planes, motorcycles
95 - violin, drilling
90 - dog barking, yelling, train whistle, lawnmower

Slightly Irritating Noises
85 decibels - saw, mixer
80 - alarm clock, doorbell, telephone dial tone, dishwasher
70 - loud television, vacuum cleaner, piano music, passing cars

Comfortable Noise Levels
60 decibels - hens clucking, normal human conversation
55 - coffee maker
40 - cat meowing, wild birds
30 - background noise, whispering
10 - a leaf falling, breathing
0 - near total silence

And my hearing is at 90 decibels, and the only thing I can hear is when my dog Skye barks... i feel the vibrations from lawnmowers,train whistles are to high pitch - can't hear them, and it depends on who's yelling - without my hearing aid. Interesting, that means a crow would probably be able to wake me up!

I wonder why there ain't any breeders who established a chicken breed with roosters that are kind and crow less loud. Like max 100dB. I can keep such a rooster and would certainly be interested to buy such breed.
