A sound level of 76.5 dB is considered moderately loud. It is comparable to the noise of a busy restaurant or a vacuum cleaner. Prolonged exposure to sounds at this level may cause some hearing discomfort, but it is generally safe for short durations. For context, normal conversation typically ranges from 60 to 70 dB.

It is difficult to be specific because busy street traffic and quiet radio are not standard volumes of sound.However, a quiet radio - at around a "normal" conversation level is 60 decibels (dB). A busy street is can range from the low 70 to high 80 dB. Let us say 80 dB.The difference is 20 dB = 2 Bels. This means the street is 10^2 = 100 times as loud.
Half as loud in decibels is about a 10 dB decrease. For example, if a sound is initially at 70 dB, half as loud would be around 60 dB.
100 dB
A avalanche can range from 100 dB to 180 dB
A sound that measures 55 dB is considered moderately loud, similar to a normal conversation or background music.
100 dB is considered very loud and can cause hearing damage with extended exposure. It is approximately as loud as a chainsaw, a jackhammer, or a rock concert. It is recommended to use ear protection in environments with noise levels reaching 100 dB.
A noise that is 55 decibels loud is considered moderate in volume.
94 dB is considered to be loud and can cause hearing damage with prolonged exposure. It is similar to the noise level of a motorcycle or a lawnmower at close range.
1100 dB is an extremely loud sound level that is far beyond the threshold of human hearing and can cause immediate and severe damage to the ears.
The loudness of sound waves is measured in units called decibels (dB). The range of decibels humans can typically hear without discomfort is around 0 dB to 120 dB. Sounds above 120 dB can cause hearing damage.
That's the sound of the Earth disintegrating.
About 132 dB(A)
The sound pressure of 45 dB is about a quiet library and 50 dB is about an everage home.
