What is dB HL?

dB HL is a unit of measurement that is used to express the softest sound that a person can hear. dB HL is a relative measure of hearing loss. 

What does dB HL stand for?

dB HL stands for decibels hearing level. It is a unit of measurement that is used to express the softest sound that a person can hear. 0 dB HL is the softest sound that can be heard by the average person with normal hearing. It is not the absence of sound, as persons with better than average hearing will have thresholds lower than 0 dB HL (e.g. -10 dB HL).

What is the normal hearing level dB HL?

The normal hearing level for most frequencies ranges from 0 to 20 dB HL. This means that a person with normal hearing should be able to hear sounds at these frequencies at or below these levels. However, it is important to note that normal hearing levels can vary depending on the individual and the frequency of sound being tested.

dB HL is measured using an audiometer. An audiometer is a device that produces pure tones at different frequencies and intensities. The audiologist will present the tones to the person being tested and ask them to indicate when they can hear them.

What does 70 dB HL mean?

A hearing level of 70 dB HL means that a person can hear sounds at 70 dB HL or louder. This is considered to be a moderate hearing loss. People with this level of hearing loss may have difficulty hearing soft sounds, such as a whisper or the ticking of a clock. They may also have difficulty understanding speech in noisy environments.

What does 25 dB HL mean?

A hearing level of 25 dB HL means that a person can hear sounds at 25 dB HL or louder. This is considered to be a mild hearing loss. People with this level of hearing loss may have difficulty hearing soft sounds, such as a whisper or the ticking of a clock. They may also have difficulty understanding speech in noisy environments.

If you are concerned that you or someone you know may have hearing loss, it is important to see an audiologist for a hearing evaluation.
