Are you having trouble hearing the family when they visit? Are your friends asking you to check your hearing aid when you ask them to speak up? How annoying!
Do they act like your hearing loss is the problem? It may not be your hearing aid at all.
Let’s take at this phenomenon and what you can do to confidently yet compassionately resolve this once and for all to hear better.
A typical human conversational voice is around 60 decibels. But this can vary widely from 50 (a quiet voice) to 70 (a louder, boisterous voice).
While a 20 spread may not sound like significant variance, this is actually a massive valley concerning human-perceivable sound. A person with excellent hearing can only hear as low as 20. And we max out at around 130-140 where it’s painful. Instant and permanent hearing loss take place.
In fact, for every 10 decibels that a voice goes up, a human hears the sound as twice as loud.
To envision sound, think of a rock dropped into a still pond. As the ripples move out, they get further and apart. Eventually, they’re so far apart that you can’s see them any more.
Sound waves work the same way.
Every time you double the distance from the sound, decibels are reduced by 6. So if you’re standing a reasonable distance from 6 feet away, a 60-decibel voice will sound very close to 60 decibels when you’re wearing your hearing aid.
But if you make that 12 feet, the decibels drop to around 54. If you double the distance again to 24 feet (roughly the length across a large living room), the decibels reaching your ear have dropped to around 48. 40 would be a loud whisper.
This sound change doesn’t only impact those with hearing loss. You may just be more sensitive to it.
Another aspect of hearing doesn’t have to do with the volume at all. It’s the frequency. When people have hearing loss, they most often lose high frequency (also called high pitch) first.
This is because high frequency is more damaging to the hearing at lower decibels. Frequency is what the word sounds like. It’s how fast (frequently) the sound waves are hitting your ear.
Violins are capable of producing a frequency of over 4000Hz, which will instantly damage hearing. That’s why many professional violinists wear ear protection. Their audience most often do not.
When a person begins to lose hearing, it doesn’t likely go all at once. Instead, they lose the tiny hairs in their inner ear that pick up that frequency. This happens because high frequency is more damaging so high-frequency hair cells are the first to go.
Once these hairs die, there is no way to restore them.
They say that knowledge is power. But before you can use this power, you’ll need to communicate with your loved ones in a loving way. Open and honest communication is the best way to resolve challenges and live more happily together.
