I have a helicopter type bass tinnitus that also ramps up with noises and cut´s through pretty much everything. I have have trouble with low frequency background noise (traffic, compressors, air conditioning, vehicles, etc... and oh yes helicopters) and it sounds like drumming in helicopter as...

Unfortunately I don´t have much answers, I can only guess what causes it. For me, I think it´s a combination of hearing loss and tinnitus, like listening something through a broken speaker. Having something like this in everyday sound range (20Hz to 1kHz) just makes it more easy to get exact...

@Rinz I have this vibrating sensation with various frequencies between 20-200hz. It's like I would hear another sound on top of the original sound, which makes these sounds that are usually considered soft background sounds very noticeable. I guess it's my tinnitus what I hear on top of them...

Handicrafts and photography are good ways to spend an hour or two.

I meant that there are two different concepts here that can be both measured in Hertz. 60bpm or 100bpm, which more often used scale for heart rate, would translate to 1Hz or 1,7Hz if we wish to present it in Hertz (like it was done in the picture). By 100Hz sound I meant that a single beat...

Yes and No. Frequency in Hz is used to tell the amount of occurrences per second. If our heart beats 60 times per minute, or once per second, then it beats with a frequency of 1Hz. The frequency of the sound that is typically associated with heartbeat isn´t 1Hz, it´s probably somewhere around 100Hz.

Occupational safety standards and recommended levels for noise differ from country to another. I think it´s a sign that we just don´t know all the factors that that are involved causing hearing loss and tinnitus.

I believe that our ears also need to get some rest and silence as we sleep. Could you set the masking sound off with timer and sleep the rest of the night without it. I can't mask mine, so I just wonder what the factory is manufacturing this time until I fall asleep.

@frischky This happens to me a lot too. There are some helicopters that fly low over the area where I live. The few heaviest are twin engine Eurocopters from the same era, but four times heavier and have four times more powerful engines than AS350 has. They are quite loud as the rumble of the...

It could be that contracting muscles vibrate and occluded ear makes the rumble that these vibrations create louder and more audible.

@TheDanishGirl have you tried different tints on sunglasses? For me some tints can enhance the contrast but still make the floaters less noticeable.

As far as I know, one of the differences using telephone speaker, on-ear headphones, in-ear headphones and loudspeakers is how they create the bass frequencies. Loudspeakers move a lot of air with big drivers, while headphones take advantage being closer to the ear and can create bass...

EU is also a bit more conservative. In European union, EU-Directive 2003/10/EC sets the lower action limit value to LEX,8h to 80dB(A) and Lcpeak to 135dB(C). One of the actions that needs to be taken when one of these lower action limit values is exceeded is to provide the hearing protectors for...

If people accept the "gating mechanism" hypothesis, isn´t that essentially same as accepting the fact that tinnitus is a result of genetic variation. From my point of view it would be then irrational to assume that everybody has exactly the same response to same level of sound. Stress and...

Defining everyday sounds can be a bit ambiguous. For example, it´s winter here and the snow plows are an everyday thing. Most people don´t mind (or cover their ears) while there´s a snow plow removing the snow from the road or from the sidewalk, even if they would pass less than a meter away. I...

There is a peak measure for instantaneous impulse noise, LcPeak, and that is measured in C-weighted decibels, unlike the 8 hour weighted noise exposure that is measured in dB(A). In EU the limiting value for the LcPeak seems to be 140 dB(C). The directive can be found here...

Crossword and other word and number puzzles. I like to do the paper versions.

@Kates I also have thumping in my other ear when I´m exposed to certain low frequency sounds. I also have low frequency T. I haven´t really figured out whats causing this thumping for me, as I can think many reasons for it like: TTS, pulsatile T beating with external sound, neck tension, hearing...

@ashlee I find my low tones harder to deal with than higher pitched T. There's quite a lot of low frequency noise everywhere, and then the recruitment comes into play, and these sound won't blend into the background noise that well anymore.

I have bass frequency tinnitus and I also hear bass frequencies "louder". I believe for me it's hearing loss and recruitment (i.e. sound going from non-audible to loud faster than normally) that comes along with it, that makes certain sounds uncomfortable.

I have sub bass T and high frequency T too. If I try to mask, the low freq T is above the masking sound or the recruitment and distorted sound that I get on many bass frequencies makes the masking sounds pretty much useless.

It's strange that people in general are more aware about habits and foods etc. that might affect their health, but blasting headphones or otherwise noisy lifestyle doesn't seem to concern people that much.

Tinnitus rates around 10% seem to be often quoted for the whole population. Studies covering certain subgroups like elderly people and military personnel often seem to report higher rates, even high as 20%. It would be interesting to know what is the limiting value for percentage of people...

Recent study published in Military Medicine Journal finds that the tinnitus rate among French Mountain Artillery regiment soldiers is 19%. Abstract: https://academic.oup.com/milmed/article-abstract/183/9-10/e302/4954109

Maybe there are some hearing loss and tinnitus studies that cover for example commercial airline pilots. They have gone through long training, need to memorize and control various things all the time, and work in relatively noisy environment. They most likely also endure some work related...

One of the most exclusive jobs in the world gives the opportunity to operate and be onboard one of the noisiest things in the world: Space shuttle.

Hi @ClubRacer. Sound is basically created by vibrations. If the engine and tyres make the car to vibrate heavily, the vibrations can create some additional sound pressure in low frequencies, along with the normal noise from the engine and tyres. We hear low frequencies generally softer than...

Some bikes are a bit too loud for my taste, but those 80/90's powerboats with twin V8 engine and no muffler are even more ridiculously loud!

@Berik As far as I know, threshold of pain varies from person to another, and it's also depends on the frequency and the spectrum of the sound. It's quite hard to give a single value for noise pain threshold, but if a single value is given, it's usually somewhere in the range that you quoted...

Muscles vibrate as they contract. When ear canal is occluded for example by an earplug, these muscle vibrations can't freely escape through the ear canal and can be left to reverbate due to occlusion effect, and can create a rumbling sound.

I didn't say that the funding applications should contain somebody from the internet forum as reference. Of course I agree that the bigger and more expensive studies involving medical procedures should be based on existing studies and knowledge of medicine. But not all studies are big and have...

I think that it could be beneficial for a researcher to lurk here. Quite often people here, independently of each other, describe very similiar symptoms and behaviour of their tinnitus, like spikes, fluctuations, reactive tinnitus, sound distortions etc. Reading these stories where people...

@Mystery Reader Yes, basically app readings should be calibrated or atleast verified somehow. The app could be pre-calibrated for some smartphones, but as there are so many models using Android, so it's very difficult to have it pre-calibrated for all models. I guess, if one wishes to estimate...

There's a wide range of earplugs to choose from. Some models, like transparent silicone earplugs are very hard to notice if there's no close image of the ear.

I experience this with some tones. A rapid drop in ambient sound volume, just like turning the running faucet off, makes the tone to appear somewhat more noticeable for a few seconds. I don't know if there's scientific explanation for this. Maybe it's just that the auditory system needs some...

Most sound pressure level meters (the real devices, not apps) seem to have their upper limit ~130dB. Otherwise, they'll cost a fortune. I'd guess that the peak SPL could be higher than that.

I'm not blaming you. I'm just saying that if more awareness preventing hearing loss and tinnitus is wanted, then the problem should be looked from all angles. And I find that this problem is very rarely looked from this angle, even when it could be easily done.

To start, I agree with you with this. It's more this general awareness about sound levels that I'm thinking. The A-weighting is so deeply rooted into the system, as it has been the main scale used to measure sound exposure for decades, that changing the way sound exposure is studied and...

@Ed209 Just as a general comment to this subject, I find it a bit confusing that, as far as I know, NRR is calculated from C-weighted measurements and so it applies to C-weighted measurements, while A-weighting is the scale where the regulations are usually given. From the user persective...

That rumbling vibration is one of the tinnitus tones I hear.

I think good advices have already been proposed in this thread. I was just trying to say that from 15m away the sound pressure level is (in theory) already much lower. The attenuation that comes with this distance vs bike passing from 1m is already more in the range below 1khz than what...

The theoretical sound pressure level 15m away is approximately 20dB less than it would be 1m away from the motorcycle (in a open space above hard ground). Just for comparison, chainsaws usually create sound pressure level that is around 105-110dB(A) at the level of user (ears), when they are...

Yes, too much of anything is a bad thing. High pitch T cuts through everything and is painful. On the other hand, low frequency sounds are always present atleast if there's some traffic or home appliances nearby, so it's still it's like listening your T through a broken speaker all the time.

I'm sorry to hear that. I have also low frequency T, and it reacts to other low frequency tones as well, so I know the feeling. I bought a dB-meter with C-weighting ( dB(C) ), to get some idea how loud these sounds actually are. (dB(C) derates low frequencies much less than commonly used dB(A)...

They probably are quiet in our A-weighted world. Some AC's can have a rumble for example around 40hz, which can be quite heavy if one is for example sensitive to sound or has low frequency T/hearing damage. A-weighted decibel scale derates the sound pressure level in this range around 30-35dB...

Does it help if the "in the ear" aid is like a silicone plug with multiple holes? (Probably not for the irritation part, but for the other things you mentioned)

Trying to get good sleep and sleep patterns might be a good idea to get more relaxed feeling and to give your system possibility to adapt to the situation.

Yes, and based on what I've read on this forum, it seems to be quite common.

I believe there is more and more awareness in general population that prolonged exposure to loud sounds can cause hearing damage and tinnitus. I just don't know how effectively people who don't have T apply this information, because "trial and error" is one of the most efficient methods to learn.

I think I understood what you said very well. I agree what you said in the quote above. Perception can change due to stress and other obsessive behaviour. I just find it hard to believe that a permanent memory record is made, depending on what one does in the early phase. But according to your...

I find it hard to believe that it would be so easy to find counterexamples if this would be the whole truth. What about those that develop tinnitus gradually because of long term exposure to noise? They don't probably stress about as it much but still got T. And lot of people with disco T...

Maybe it's because of something like this: https://www.tinnitustalk.com/threads/comt-and-the-neurogenetic-architecture-of-hearing-loss-induced-tinnitus.29512/ Maybe in future we know.

You may find Tinnitus Hub survey helpful. There are some statistics about the causes that survey participants have reported: https://www.tinnitustalk.com/threads/tinnitus-hub-talk-survey-results.14295/

I don't know how loud crickets can get, but could it be that these things are unrelated? Could it be just the walking and the exercise that gets your T to spike, just like a regular exercise spike, and you can hear this new and fading tone for a while? New tones can be a bit unstable in this sense.

When you wear earplugs, the occlusion effect makes your internal sounds louder. Have you tried different sleeping and head positions to help the air flow more freely, and maybe to reduce the snoring.
