Decibel levels2/21/2023 ![]() ![]() This vibration is transferred to the inner ear. ![]() It vibrates in answer to the sound and this causes vibration in the chain of the three bones in the middle ear. The eardrum is the start of the middle ear.Normal hearing occurs when sound enters the outer ear, travels through the ear canal and reaches the eardrum.How many vibrations is frequency per second? For example, 20 Hz means 20 vibrations per second. It is measured in Hz, which is named after the name of the German physicist Heinrich Rudolf Hertz. The frequency describes how high the sound pitch is. The level of the sound pressure is measured in decibels (dB). The frequency describes the pitch of the sound. Alexander Graham Bell invented this unit. The word “decibel” comes from “deci” (meaning “one-tenth”). The volume of sound or a loud sound is determined by the level of pressure. While 20 to 2000 Hz forms a human hearing range. ![]() Our hearing is most sensitive at the level between 2000 – 5000 Hz frequency range. On the other hand, the range of human hearing at the highest possible frequency heard without discomfort is 20,000 Hz. The level of a pitch of the sound is measured in the decibel (dB) and the level of loudness is measured in Hertz (Hz).įor a normal person hearing range starts low about 20 Hz. The human hearing range depends on the pitch of the sound whether it is low or high. It’s important to remember that hearing inability is different for different people and even has different levels. There is Severe deafness, wherein a person cannot hear loud speech without the usage of hearing aid. Normal hearing is important for language development, social communication, gaining new knowledge and responsiveness to environmental sounds. A decibel is a unit of measurement of the loudness of the sound. We are always here to help you.ĭecibel level for normal hearing ranges from 0 to 20 decibel. ![]() What ever you’re looking for, you’ll be able to find it.You can purchase the latest hearing aids at a fair price through HearingSol, If you need more information or you have a query about Decibel Level for Normal Hearing or Hearing Loss, just give us a call on +91-9899437202.
