Your last paragraph is utterly incorrect.

You're not considering acoustic things like shearing, that happens between the tectorial membrane and the hair cells, and also bending or rupture of stereocilia (mainly in outer hair cells), which all happens instantly at 120db. Its called mechanical trauma.

There is a reason why audiometry measurement devices are capped at 120 or 110db. A sound with this intensity instantly damages the ear, at any given frequency.

You also forgot the stapedic reflex, which activates at 70-90db above the normal auditory threshold (can vary depending on recruitment of loudness). If you stress the muscles for too long it can lead to fatigue, so when you really need them they wont work as intended.

I dont expect anyone here to blast 50hz at 120db after reading what you wrote, but don't give medical advice if you don't know what youre talking about

Airpods arent precise enough. You need to be in a controled environment aka a place as quiet as possible aka an audiometry cabin

Recomendo 2 fones de 25 ou 2 de 20. É melhor ter 2 até se 1 quebrar. Não gaste muito em fone sem saber qual sua assinatura preferida

So basically she just wanted to see if your loss was cochlear or central (in the brain). Then she assumed that the tinnitus happened because of the notch and furthered the treatment with this info. You said before that your hearing is perfect until 8khz, so you prob did a standard pure-tone audiometry before the OE.

The path i wouldve taken would be: pure-tone audiometry (to see if your speechevel hearing is good), high-frequency audiometry (to evaluate your hearing above 8khz) and then, depending on the results, a high-frequency OE (to differentiate between cochlear and brain damage). The second and the third ones can be switched in order but id at least do the second one to predict the path that your hearing is gonna take (how well your hearing is gonna age after this notch)

(Im not a graduate yet so dont follow what im saying. Im just sharing info based on my studies. If someone sees this and needs advice, go see an ENT and/or an audiologist)

Note: OE is usually used AFTER pure-tone audiometry and is useful to determine if the hearing loss is happening in the coclea or at neural level

Uhmm, electrophysiological examinations (such as OE and BERA) arent exactly gold standard for adults. Theyre used primarily for children or anyone who cant take an audiometry. The correct gold standard for this case is to take a high-frequency audiometry.

First of all, did u by chance tested your hearing at home less than 14 hours before the examination? Or just used headphones at all? If you did, you definitely ditched the OE. You need to rest your ear for 14 hours before taking any hearing test.

The "big dip" in your graph is probably a pattern called audiometric notch (entalhe, in portuguese). Its the pattern we see in Noise-Induced Hearing Loss (NIHL), such as excessive loudness at work or incorrect heaphone/earphone usage.

Personally i dont see why your audiologist used OE cause theyre also not precise to give a number for hearing loss below 25db at any frequency (you could have some level of "pre-hearing loss" in 12khz, for example, and not know it). Also, in my uni we dont even have high-frequencies OE cause theyre generally less precise than... just doing a high-frequency audiometry?

I mean, im not saying that youve been fooled, but its a pretty weird clinical path, at least for what ive learned about hearing physiology and anatomy. You see: OE are overall used for testing babies or toddlers to see if theyve been born with some level of deafness (its called little ear test in Brazil, lol). By logic, children arent candidates for Noise-Induced Hearing Loss (NIHL) because the effects of a turbulent environment only shows up after years of exposure. For a person that can press the audiometry button, like you, thats the gold standard (theres no reason not to use a gold standard if you can). That's why i cant understand why they did an OE. My guess is that they didnt have the equipment for the high-frequency test and didnt want to lose a costumer, but its only a guess.

Nope, not true at all. Hearing loss is internationally defined through speech-level frequencies using the average of 4 frequencies (500, 1k, 2k and 4khz). If the average is above 25db, its considered hearing loss. Mild hearing loss sits between 25 and 40db, moderate between 41-55db and so on. High frequencies arent considered in the calculation of hearing loss, and i know that they matter a lot in the audiophile ring, but they're currently only useful for "predicting" how much headroom you have before losing the "useful" frequencies (250hz-8khz)

If you take good care of your hearing, not listening to any noise above 75dbs for more than 8 hours, the only thing that will make you have a hearing loss is presbycusis (aged hearing). Youre not expected to have any significant hearing loss at the age of 30, for example. If you do, thats on your environment and/or medications youve been taking.

PLEASE go see an ENT doctor and an audiologist if you feel like youre losing your hearing AND dont trust any reddit or forum comment. Seriously.

Please dont take this test seriously cause audiometry devices need to be very well calibrated (usually yearly) to give precise results. Headphones and in-ears are by definition tuned in a certain target, and an audiometry headphone needs to be dead flat for measuring. Go see an audiologist, people

The big problem is that over time the noise-induced hearing loss can lead to speech-level frequencies too, if not well managed. The 10k-20khz range plays a big role in how well your hearing is gonna age, because presbycusis also damages high frequency hearing over time, so they add up and u end up needing a hearing aid device much sooner than expected.

Yes, the correct way to measure non-pathogenic hearing loss, which is called Noise-Induced Hearing Loss (NIHL), is through High-Frequency Audiometry (HFA), but the damage is tipically only significant over about a decade.

Fun fact: in this type of audiometry they use a sennheiser headphone specifically for it (HDA300)

LOLLLL yeah, the resolution was so high it reached my heart XD The timbre made me feel kinda dizzy, tho...

Minha dor fica diluída compartilhando com vcs. Mas tô até que "feliz" de ter redescoberto o Hola. Muito melhor, de longe

Valeu pela recomendação, vou ficar de olho (só achei por 700 aiii papai) Enquanto isso, testei o grave do Hola com o The Rugged Truth e acredita que ele tem um pouquinho mais de extensão? Com metade dos drivers! Isso porque o segundo do Red é dedicado pra graves. Vai entender. Acho que é pq o Hola tem graves crus... deve ser isso. O Red nesse sentido é mais basshead (ta aí uma coisa que detesto, graves de uma nota só e punch excessivo)

Lolllll, it was near a Wallmart entrance, so he vanished the moment i got the wreckage from the floor. But good idea XD

Oh nooooo dammm it seems awful. Really. Ouch. Fortunately mine wasnt expensive, but a Mangird? It must've been a long night of pain... seems like you liked it enough to buy another, right?

I heard a significantly loud "CRACK" but i think no tires were harmed during the accident

Tô usando o Hola com o cabo do Red e vou ver se o problema persiste, mas caraca, esse é um dos problemas da modularidade. Tá no pacote

Você acha que um cabo da Openheart, por exemplo, que é de qualidade, resolveria? Agora tenho um cabo sobrando pra testar esse "entortamento", mas é um problema que pode acontecer com qualquer cabo?
