Decibels are in essence a measure of volume. The volume or intensity of sound is measured in units called decibels (dB), generally on a scale from zero to 140 (any higher than 140 and you are in trouble immediately). The higher the number in decibels, the louder the noise. The louder the noise, the greater the risk of hearing loss.
Loudness or amplitude is measured in decibels and it is marked or notated using dB to designate decibels. Keeping in mind that at 85 dB hearing loss can begin, normal everyday conversation is at approximately 70 dB and loud talking is about 90 dB.This is one of the reasons why loud and boisterous people bother us so much.oudness or Amplitude â Science, specifically audiology, knows that the difference between the threshold of human hearing (0 dB) and the threshold of pain (120 dB) and hearing loss occurs at approximately 120 decibels.
