What is normal dB for hearing?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
What noise level is safe for babies?
You’ll want to keep sounds around your baby quieter than 60 decibels. For comparison, quiet conversation at home is about 50 dB, freeway traffic is 70 dB, a workplace can be 80-85 dB, and a jet takeoff is about 100 dB.
When do babies start to mimic sounds?

What is a good hearing range?
about 20 to 20,000Hz
The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it’s the upper frequencies we lose first.Is TV noise bad for newborns?

Can a sound of 75 decibels cause hearing loss?
Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss. However, long or repeated exposure to sounds at or above 85 decibels can cause hearing loss.
