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.
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.
A human ear capable of detecting sound at a level of around 12 hz. A decibel is not the correct measurement unit for measuring the human range of sound.

Decibel (dB) * The Bel is the primary unit. However, the scale is too large. So for human hearing, we use the deciBel, where each deciBel is 1/10 of a Bel. this is abbreviated dB.
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.
The decibel level for standard human voices is around 60 decibels, which is also the level for singing birds. Hearing loss occurs at around 110 decibels with painful hearing loss occurring at 130 decibels.
70db to 85 db (decibel)
Does a heart make decibels? Never heard a heart.
