HOW ACCURATE IS HEARZA™?
hearZA™ – a digits-in-noise hearing test – was successfully developed and validated as a self-test on a smartphone via a smartphone application using any available headphone set. hearZA™ is able to correctly identify hearing loss with an accuracy of more than 90%.
AT WHAT AGE SHOULD I BEGIN REGULAR HEARING CHECK-UPS AND HOW OFTEN SHOULD I GET THEM?
Listening and hearing are related but different. For a message to be “heard” the brain has to pay attention to it, which becomes more difficult as we get older. At age 45, the average person has no significant age-related hearing problems with either the ears or the brain. However, a 45-year-old who has worked 20 years in hazardous noise may, in fact, have a substantial amount of hearing loss. One easy way to determine if a hearing examination is needed is to have a conversation with your wife without distractions (TV, background talking, etc.).
If her softly spoken (not whispered) message is not completely understood, it is time for an examination. Hearing loss often develops gradually and so slowly that one adapts to the change in perception without even noticing. However, once hearing loss crosses the threshold of 40-decibel hearing loss (dB HL), the effect on normal communication is very noticeable. Between 25-dB HL (the upper limit of normal hearing) and 40-dB HL, hearing may indeed seem selective.
HOW DO I DETERMINE IF I AM A CANDIDATE FOR A HEARING AID?
The critical variable is whether you experience difficulty hearing or are having increased stress and strain in your daily function. Amplification may simply relieve the strain of hearing,
