sounds people with hearing disorder can't Hear

Frequencies That are Low

Often the defect is at the opposite end of the sound scale. The low-frequency hearing loss involves sensorineural damage and impacts sound produced at less than 2,000 Hertz. Usually, low frequency hearing loss is a genetic or congenital defect such as cochlear malformation.

Soft Tones

A person with conductive hearing loss can hear most sounds if they are loud enough, but not at normal volumes. This is why amplifying the sound with hearing aids is a solution for them and why they are always turning up the TV or need headphones to hear music. The ears work if the sound is loud enough to get through. When someone speaks in a normal voice, they may hear something but it sounds mumbled.

Conversation in a Noisy Room

Sometimes, it’s what you can hear that becomes the problem. People with a significant hearing challenge will experience something call recruitment noise. In other words, the background sounds overwhelm everything else. A sound like the air conditioner turning on masks all other noise.

This background noise can be painfully loud causing physical distress, too. The phenomenon occurs when an individual has both normal and damaged hair cells in the inner ear. The normal cells take over for damaged ones close by causing the sound to be excessively loud.

Speech of Any Kind

Profound hearing loss means you don’t hear speech at all. Medical professionals use a classification system to measure hearing loss in decibels – a person with normal hearing measures anywhere from -10 to 15 dB HL (decibels of hearing loss) during a hearing test. To be diagnosed with profound hearing loss, the classification is 91 or more dB HL.

No two people hear or don’t hear the same thing regardless of their hearing challenges. It all depends on why your hearing is diminished and how severely.
