Perfect hearing is having a “0 dB” score at all frequencies. Anything below 20 dB is significantly worse than normal. A 100 dB loss at all frequencies means you hear nothing.
What is considered perfect hearing?
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.
What is normal hearing range?
between 20 and 20,000 Hz
A person with normal hearing perceives sounds at frequencies between 20 and 20,000 Hz. Frequencies between 500 and 4000 Hz are most important for speech processing.
What are the levels of hearing?
This description is referred to as “the degree of hearing loss.” It is based on how loud sounds need to be for you to hear them. Decibels, or dB, describe loudness.
Degree of Hearing Loss.
| Degree of hearing loss | Hearing loss range (dB HL) |
|---|---|
| Mild | 26 to 40 |
| Moderate | 41 to 55 |
| Moderately severe | 56 to 70 |
| Severe | 71 to 90 |

People of All ages without a hearing impairment should be able to hear the 8000hz. People under 50 should be able to hear the 12,000hz and people under 40, the 15,000hz. Under 30s should hear the 16,000hz, and the 17,000hz is receivable for those under 24.
At what age do you stop hearing high pitched noises?
Adults lose their ability to hear sounds above 15,000 Hz starting at the age of about 25. In laboratory conditions, the human hearing frequency range can go up to 28,000 Hz or as low as 12 Hz.
What are the 3 types of hearing loss?
Hearing loss affects people of all ages and can be caused by many different factors. The three basic categories of hearing loss are sensorineural hearing loss, conductive hearing loss and mixed hearing loss. Here is what patients should know about each type.
What is considered bad hearing?
Mild hearing loss: Hearing loss of 20 to 40 decibels. Moderate hearing loss: Hearing loss of 41 to 60 decibels. Severe hearing loss: Hearing loss of 61 to 80 decibels. Profound hearing loss or deafness: Hearing loss of more than 81 decibels.
What if my ears are ringing?
Ringing in your ears, or tinnitus, starts in your inner ear. Most often, it is caused by damage to or the loss of sensory hair cells in the cochlea, or the inner ear.

It turns sound vibrations into electrical signals that travel along the auditory (hearing) nerve. The brain translates these signals into recognizable sounds.
What is the meaning of audiograms?
An audiogram is a graph that shows hearing sensitivity. Along the top of the graph are frequencies noted in Hertz. A frequency is also often referred to as pitch. The higher the frequency, the higher the pitch. The sound levels measured in decibels (dB) are located on the left side of the graph.
Can you sleep with a hearing aid?
We don’t recommend wearing hearing aids in bed because they may be prone to falling out while you’re sleeping. When sleeping, your head rubs against a pillow and your sleeping positions may change throughout the night. Thus, there is not assurance that your hearing aids will stay in your ears.

A deaf person can only hear sounds at 81 dB (traffic) to 100 dB (industrial noise), explains Avner Aliphas, MD, an otolaryngologist in Newton, MA. With severe hearing loss, you need sounds to be between 61 dB (normal speech) and 80dB, Aliphas says.
