Degrees of Hearing Loss: What Level Are YOU At?

Your hearing ability determines your degree of hearing loss, from Minimal to Profound. But hearing is a complex function, unique to each person, and it often changes over time. It is critical that any change in hearing be assessed by an audiologist to determine its severity and appropriate treatment options.

How Is Hearing Loss Measured?

Hearing loss is measured by the volume of sound you can hear and by the frequency (or pitch) of the sounds you can hear (at different volume levels).

Measuring Sound Volume

Sound volume is measured in decibels (dB). Exposure to prolonged sound at 85 dB or louder can cause hearing damage. Here are some common sounds and their typical volume in decibels:

●     Watch ticking                20 dB

●     Soft whisper                 30 dB

●     Normal conversation    60 dB

●     Dishwasher                  70 dB

●     Lawnmower                  85 dB

●     Motorcycle                    95 dB

●     Shouting in your ear     110 dB

●     Standing near sirens    120 dB

Measuring Sound Frequency

Frequency (or pitch) is measured in Hertz (Hz) and is generally classified as low-pitch or high-pitch. Here are a few examples:

Low Pitch:

●     Dogs barking

●     Lawnmowers

●     Thunder

●     Consonant sounds like “j”, “u” and “z” 

High Pitch:

●     Birds chirping

●     A child’s squeal

●     A woman’s voice

●     Consonant sounds like “f”, “s” and “th”

Age-related hearing loss – known medically as presbycusis – affects many people as they get older, and normally results in a loss of hearing at higher frequencies.

As hearing diminishes, higher frequency sounds can generally be heard better at higher volumes. For example, a grandparent may struggle to hear their young grandchild’s normal speech, but can hear their high-pitched screams more easily.

Your audiologist will assess your hearing using sounds across a range of frequencies and at different volumes to determine the exact degree of your hearing loss.

Degrees of Hearing Loss

The following chart can help you understand the different degrees of hearing loss, and how they can impact a person’s life. However, it is important to remember that each person’s experience is unique, even if their degree of hearing loss is the same as another person’s. In addition, a mild hearing loss does not imply a low level of difficulty hearing or communicating. 

Consequences of Untreated Hearing Loss

No matter how mild your hearing loss, it is important to discuss hearing solutions with your doctor of audiology. Untreated hearing loss, even when mild, is associated with cognitive decline, including dementia and Alzheimer’s disease. Hearing loss is also associated with depression and anxiety, social isolation, and fatigue.

Treatment For Hearing Loss

All degrees of hearing loss can be treated with appropriate hearing aids, and there are a variety of hearing aids on the market to suit different degrees of hearing loss, activity levels, interests and lifestyles.

Talk to your audiologist if you (or a loved one) are having difficulty hearing. Treating your hearing loss with an appropriate solution isn’t just good for your hearing, it’s good for your overall health, well-being, and quality of life!
