Last week I went to have my hearing tested at my local ‘Specsavers’ who, if you didn’t already know, also have in-house audiology experts providing hearing tests.
I was met by a lovely lady called Sue, who began by asking me some questions which she filled out in a form. The main question being – “what is the reason for your visit, do you have reason to believe you are having a problem with your hearing?”.
My honest answer was this… “my wife booked me this appointment, because I seem to be having difficulty hearing her and the kids when they are talking to me. I sometimes find my colleagues are all shouting ‘Matt!’ at the same time, to get my attention. To be honest, I think I am just zoning out – I tend not to be able to hear anything if I am concentrating hard on something. Also, I am in the field of acoustics for work and now that I am 40 years old, I know it is a good idea to get my hearing tested”.
With questionnaire complete, I was asked to take a seat in a small audiology booth (which I believe was an IAC acoustics Audiometric room) and put some headphones on. I was given a large button at the end of a lead and told to press the button when I heard a tone / sound and hold it until the tone / sound had stopped.
The test lasted about 10 -15 minutes. I would hear the tone on one ear, and I would press the button and hold it until it stopped. Some were very high pitched, some low, most very quiet.
Then came the results!!…. Sitting back with the audiologist, she showed me a graph on her computer screen. Print out of results below: –
The numbers on the left show the dB level (or loudness) of the sounds played in my headphones. The numbers on the bottom represent the sound ‘frequencies’. The lowest numbers on the left of this X axis are low frequencies (think booming low voice of a man like Brian Blessed) these numbers then increase to the high frequencies up to 8000 Htz, which is a very high pitch, but a pitch you should be able to hear if you have no hearing impairment.
The ability to clearly hear high frequencies is important for hearing speech. Particularly the consonants like T’s and S’s. Vowels tend to be ‘lower’ frequency tones when we say them, when you say them you can hear that “T,T,T,T” – it’s a higher frequency sound than “O,O,O,O”. If we can’t hear high frequencies very well, we tend to struggle with conversation as these consonants often help form the words identity. As we get older, our ability to hear high frequency sounds deteriorates.
Anyway, back to my results. To cut a long story short, anything above a 20 on the Y axis means you have normal hearing. As you can see, my results are comfortably above this line. Sue said, “this is probably the best hearing test result I have had in a long time”. She did caveat that by saying her average customer is about 60 years old, but it seems I do have very good hearing after all.
My wife laughed when I told her. “No excuse whatsoever for ignoring me now when I am trying to get your attention”.
