Hello,

Long time no see, though I regularly visit these pages but just don't post much.

Anyway, I am kind of curious about something. We live in my opinion a noisy world and exposed to loads of potential for hearing loss. I hate people for example slamming doors and I can't stand it when trucks, scooters and ambulances with their sirens blaring are in traffic. I tried an online hearing test. This one:

I discovered that I couldn't hear the 8 KHz tone. I don't know if I should be worried because it seems to me that only bats and dogs could hear that one. Can anyone else here hear it?

I can hear the 8KHz tone just fine through my laptop speakers (what are you using to listen?). That seems quite a low frequency to not hear...most people can hear beyond 12KHz I would have thought, and kids beyond 16KHz.

My ears are 39 years old and taken a bit of a battering, so if your not hearing the 8KHz tone you might want to think about getting a proper test done and see if there is anything that can help.

Cheers, Wayne.

I am using crappy old cheapo headphones but at a volume that is barely audible as the test suggested with the test tone. So I have the test tone at a volume I can barely hear then listen to the rest. The 8KHz I couldn't make out. It is very high pitched and obviously too high for me to hear at the conditions I set myself. Did you have the test volume at barely audible? If I set it on a higher volume I hear it, but as I said it is very high pitched.

i can hear it.

8 kHz is alarming low!

I'd be a little worried. It may be a good reason to get a checkup, just to be sure it's nothing serious.

Thankfully, I could hear it quite easily with better quality headphones. I was starting to panic. The headphones I used before were crap and probably shouldn't be used for that kind of test, though my missus could hear it with the crappy phones whereas I couldn't.

If the headphones are not linear frequency vice, then any given frequency can be harder or mroe difficult to hear.

yeah - there might be a 'response-valley' right at 8khz
when I was younger I occasionally made the 'ultimate' quick hearing check in the hifi departement with some cheapo fm radio - 'cheapo' was important, as those didn't suppress the 19khz auxiliary signal from the fm transmission... it was clearly audible, but it's a very unpleasant tone
(today that test would probably be pointless for me...)

cheers, Tom

hm, there is a plug that produces test signals...was it Optimaster? must be another plug yet, dunno.

ControlRoom in the mixer folder

hey thanks Immanuel...almost never use that thing, so I forgot
