Well, you finally did it.
2
You got a brand new pair of hearing aids and they have all of the bells and whistles.
3
They have a deep neural network for artificial intelligence sound processing.
4
They're rechargeable batteries.
5
You've got the new form of LE Audio Bluetooth, which enables a feature called AuraCast, and they're even waterproof.
6
So why the heck do they sound so freaking tinny?
7
Hey guys, Cliff Olson, Doctor of Audiology and founder of Applied Hearing Solutions in Phoenix, Arizona.
8
And this is a question that I get all the time about the sound quality of hearing aids.
9
So in this video, I'm gonna explain exactly why your hearing aids sound so tinny, what's causing it,
10
and what you can do to fix this problem to make your hearing aid sound as natural as humanly possible.
11
So here's the deal.
12
To truly understand why hearing aids sound so tinny to some people, you really have to have a good understanding of hearing loss in general.
13
When people start to lose their hearing, it's usually the high frequencies that decline first.
14
When this happens, you typically start to notice that you can hear that people are talking, you just can't quite understand what they're saying.
15
It's a clarity issue, not a volume issue.
16
An easy way to explain this is if you turn up the volume on the TV, it typically makes things louder but not clearer,
17
especially if you're watching a show that has accents.
18
Like the popular TV shows Outlander with their Scottish accents or Peaky Blinders with their English accents.
19
This problem is even more apparent inside of noisy places like restaurants, where you have all this restaurant noise that you can hear just fine,
20
but you have trouble understanding the person who's right across the table from you.
21
This loss of high frequency hearing is caused by the deterioration of hair cells inside of your cochlea, which is your hearing organ.
22
Let me give you a really quick anatomy and physiology lesson as to how this works.
23
When sound enters your ear, it travels down the ear canal and vibrates your eardrum.
24
Those vibrations are then passed through three tiny bones in your middle ear space called the malleus, the incus, and the stapes,
25
and transfer that vibration of sound into the cochlea.
26
Your cochlea is tonotopically organized, which means that different regions inside of the cochlea respond to different sounds, but these high -frequency sounds,
27
up to 20 ,000 Hz, are at the base of the cochlea, which is right where the sound enters.
28
If we take a look inside of the cochlea, we will see that you have different hair cells,
29
and the hair cells that I'm specifically talking about here are the outer hair cells.
30
Their job is to amplify those tiny vibrations of sound so they're strong enough to activate the inner hair cells,
31
which then send signals up the auditory nerve to the brain so you can hear.
32
But as these high -frequency outer hair cells become damaged, they can no longer provide this natural amplification effect.
33
Without enough vibration, many of those high -frequency speech sounds never activate the inner hair cells, so speech information never reaches your brain.
34
So what speech information is actually missing when you have a high -frequency hearing loss?
35
For this, let's briefly look at an audiogram.
36
For this typical high frequency hearing loss, any of the speech information that is above the X's
37
and the O's in the shaded gray region can no longer naturally be heard by this individual.
38
Any of the speech information below the X's and the O's in the white region can still be heard naturally.
39
The high frequencies on the right hand side of the graph have most of your consonant sounds
40
that provide the perception of clarity in speech.
41
And the low frequencies on the left hand side of the graph have most of your vowel sounds
42
that provide the perception of volume in speech.
43
For a visual example, which word do you think this is?
44
Is it fat?
45
Is it sat?
46
Is it cat?
47
Or is it even a four -letter word, chat?
48
When you have a high -frequency hearing loss, it could literally be any of those options and more.
49
Which is why it's important
50
that hearing aids amplify sounds in these high -frequency ranges to restore your access to this speech information.
51
But what does all of that have to do with your hearing aids sounding tinny?
52
Well, it has everything to do with it.
53
You see, when you use hearing aids to amplify these high frequency sounds to restore clarity,
54
it can also cause a tinnitus perception for two main reasons.
55
And reason number one is that your hearing aids are not programmed correctly.
56
The good news is a hearing care professional does not have to guess as to whether
57
or not your hearing aids are programmed the right way.
58
They can just verify it with real ear measurement.
59
Real ear measurement is a verification technique
60
that a hearing care professional can use to see
61
if your hearing aids are properly amplifying sound for you to your hearing loss prescription.
62
They can see if some sounds are being overamplified in certain frequency ranges, and they can see if sounds are being underamplified in other frequency ranges.
63
To perform this verification procedure, they have to place probe microphone tubes inside of your ears along with your hearing aids.
64
They then play a calibrated sound from a speaker in front of you
65
and measure how much amplification you're receiving from your hearing aids by plotting it on their computer screen.
66
Anywhere the solid amplification curve is above the hash mark prescription curve,
67
it means that you're being overamplified and anywhere the solid curve is below the hash mark curve, it means that you're being under amplified.
68
Now let's get to the tinny perception.
69
If you have a tinny perception of sound, chances are that you're being over amplified in your ear resonance range.
70
You see, when sound enters your ears, it receives a natural boost in amplification around 2700 hertz.
71
On average, this natural amplification effect adds up to 17 decibels to an incoming sound.
72
And I don't want to spend too much time explaining what decibels are, that's definitely a topic for another video, but 17 decibels is a lot.
73
And if this is unaccounted for when it comes to programming the amplification levels of your hearing aids,
74
you're going to be significantly over amplified between 2 ,000 and 4 ,000 Hertz on average.
75
But the only way to even know this is if you measure it with real ear measurement.
76
This is what an unaccounted for resonance peak looks like that causes a significant increase in the tinniness perception of sound.
77
You see this bump right here, where it peaks above the hash mark curve?
78
This is a resonance peak.
79
And for this individual, it would make their hearing aids sound incredibly tinny.
80
But once corrected for, it should look more like this.
81
This would likely take away all of that tinny perception of sound while still keeping speech clear.
82
Without real or measurement, neither you
83
or your hearing care professional has any clue as to whether or not you're being overamplified in this range.
84
And it essentially turns your hearing a programming session into a guessing game,
85
where they're having to use trial and error to try to figure out which frequency ranges are being overamplified for you.
86
And what they inadvertently end up doing, even if they get rid of the tinniness perception,
87
is that they're then under -amplifying you in other frequency ranges, which is destroying your ability to hear optimally.
88
The same thing is true even if you don't get a tinny perception of sound.
89
You never really know if your hearing aids are programmed the right way.
90
So if you're going to a hearing care professional who is not performing real -ear measurement when programming your hearing aids,
91
it's probably time to find a different provider.
92
And if you want to guarantee that you can find a provider who performs this critical verification procedure, make sure that you check out my website,
93
hearingup .com, and find a HearingUp Network member in your area.
94
Every hearing aid member has been vetted for their commitment to following comprehensive audiologic best practices,
95
including real ear measurement, to ensure not only that your hearing aids do not sound tinny, but that you're able to hear your absolute best.
96
Now, in addition to this resonance peak issue, there is another programming error that usually causes this tinny sound perception,
97
even if you've corrected for the resonance peak, and that is not properly blending the amplification from the lows through the mids and into the highs.
98
If your hearing aids are only amplifying the high frequency ranges for your hearing loss, but you don't properly blend the amplification into the high frequencies,
99
a lot of the times this can make your hearing aid sound tinny.
100
Of course, real ear measurement is also the solution to this problem
101
because it allows a hearing care professional to see
102
if they're also giving you enough of this blending through the lows and the mids.
103
But what if your hearing aid programming was done correctly with real ear measurement
104
and they corrected for your residence peak and they corrected for the blending of the lows, the mids, and the high frequency amplification levels,
105
but you're still getting this tinny sound perception.
106
Well, that could lead to the second reason why your hearing aids sound tinny, which is lack of auditory adaptation.
107
You've got to remember that if you have a high frequency hearing loss, chances are you have not heard those sounds in a long time.
108
And research tells us
109
that it takes only approximately 30 days with a mild level
110
of hearing loss before your brain starts to change the way that it processes sound due to this auditory deprivation.
111
And on average, most individuals have had hearing loss for several years before they start to even realize it.
112
But by that time, auditory deprivation has definitely set in,
113
and other areas of your brain start to overtake your auditory cortex and use that space for something else.
114
And when you bring back all of these missing sounds at once and your brain's not ready for it, you can get this tinny sound perception.
115
The good news is research has also indicated
116
that it takes your brain 30 days to revert back to the way
117
that it was as long as you're treating your hearing loss with hearing aids that have been programmed properly.
118
Inside of this first 30 days, your hearing aids may sound a bit tinny,
119
and that's okay, as long as that tinny sound perception is not being caused by improper programming.
120
Now, if you've been wearing your hearing aids for 30 days, and you've been very consistent day in, day out, and wearing those hearing aids,
121
and you're still getting a tinny sound perception, then your hearing care professional may have to taper off the amplification levels of the high frequencies.
122
You just have to be careful because you could be trading one problem for another.
123
If you turn down the high frequencies too much, yeah, it'll get rid of the tinny sound perception,
124
but it could also take away your clarity in speech.
125
So if you have to take this approach because you just can't stand that tinny sound perception from your hearing aids,
126
make sure that your hearing care professional takes it very slow one decibel at a time.
127
Now to finish this off, one thing that you really need to understand here is that when you have a hearing loss,
128
it means that you have damage to your auditory system.
129
It may not be possible to completely eliminate the tinny sound perception of your hearing aids and still maintain good speech clarity.
130
But as long as you're aware of this relationship between high frequency amplification with hearing aids and a tinny sound perception,
131
you have a much better chance of getting rid of that annoying sound and still hearing really well with your hearing aids.
