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.

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.
On average, the human threshold for pain from sound is around 120-130 decibels. However, sustained exposure to sounds over 85 decibels can cause hearing damage over time.
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 relationship between sound intensity and the logarithmic decibel scale is that the decibel scale measures sound intensity levels in a way that reflects the human perception of sound. Sound intensity increases exponentially on the decibel scale, with each 10 decibel increase representing a tenfold increase in sound intensity.
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.
Does a heart make decibels? Never heard a heart.
Decibel is a unit used to measure the intensity of a sound, while loudness refers to the perception of sound intensity by the human ear. For example, a concert may have a high decibel level, resulting in a loudness that can be uncomfortable for the audience.
