@Kam75, how are things with you? How's the tinnitus? How's your sleep? I re-read my earlier posts here, and I think what I wrote about sleep and the link is spot-on. Stage 1 (N1) is the lightest stage of sleep and occurs as a person first falls asleep (1 to 7 minutes). Stage 2 (N2) is where...

No, it’s not strange. Hearing tests done by audiologists who sell hearing aids do not record enough data points or cover a wide enough frequency range to give accurate information about your hearing loss. You need at least four data points per 1000 Hz, and you also need to extend the test to...

You would want to know if your hearing aids are programmable to increase only frequencies where you have hearing loss. For example, I have moderate hearing loss at 4250Hz +/- 250Hz. I would want to increase the volume just in this range. In both ears. I also have catastrophic hearing loss...

Tinnitus occurs when the brain “turns up the gain” in response to a loss of signal input from severely damaged hearing cells. At the same time, the auditory system tries to recruit alternative hearing cells around the damaged frequencies, so that non-native cells send signals to the brain for...

Tinnitus that develops after noise trauma is caused by the brain's response to the loss of input from damaged hearing cells. Cutting the nerves to or from the ears in order to induce deafness will not help. In fact, some deaf people also experience tinnitus. Tinnitus can be viewed as a form of...

Foam earplugs with an NRR of 33 provide basic protection. However, NRR 33 is a laboratory-tested rating, which differs from real-world sound exposure. OSHA recommends adjusting this value to better reflect actual protection. The process is as follows: Subtract 7 dB from the NRR rating. Reduce...

A short summary of this paper: 1. Tinnitus is associated with abnormal neural activity in the brain, particularly in the auditory cortical regions, though not limited to them. 2. Tinnitus is a central nervous system disorder (and may be considered a form of brain injury), but how or whether...

70 decibels is the threshold where hearing cell damage begins. Hearing cell damage is cumulative over time with continued noise exposure. Each episode of tinnitus you experience is an indicator of excessive noise exposure and hearing cell damage. Every recurring episode of tinnitus suggests a...

I used an ACRN protocol. I think five or seven tones were played in the repetitive sound therapy. Two or three of the sounds were higher in frequency, and two or three were lower than my tinnitus frequency. The problem was that my tinnitus is in the region where my hearing is deteriorating...

This is not unusual. Your tinnitus is reactive. My own tinnitus researcher in 2024 commented that tinnitus is often quiet in the morning, then gets louder in the evening and is loud at bedtime. Tinnitus reacts to everyday noise by increasing in volume. Since you don’t have loud tinnitus at...

Your audiogram indicates hearing loss. No question. I would say a significant amount of hearing loss. My next question would be, how old are you, and what kind of work or recreational activities resulted in this level of hearing loss? An assumption about the true state of your hearing based...

@crappymate, White noise occurs when the brain produces many tinnitus frequencies as a result of significant hearing cell damage (hearing loss) across a wide range of frequencies. You may find a narrow band within your hearing loss range where the loss is greatest. Use this “highest level of...

@Kam75, how are you doing now with everything? How’s the tinnitus? How’s your sleep?

An update on the tinnitus and sleep problem. This morning, as I woke up, I noticed my tinnitus was at a reduced volume. As I became more awake, the high-frequency tinnitus grew progressively louder until it reached its usual high volume. The whole process took only a few seconds. It seems...

@jennyb123, Presenting an audiogram on a log scale is misleading. Your chart shows data points at almost even spacing, while in reality there is a large variation in frequency intervals along the x-axis. I have replotted your audiogram (IMG_3235.jpg) on a linear chart (attached) so you can...
