Hearing aids are not protective devices and are not rated for hearing protection. Hearing aids are vented to allow for pressure changes and to allow sound into the ear that is still in your audible range. Unless you have un-vented hearing aids designed for hearing protection, you are not protected.Grouse Feathers, if you had ever been in the situation to wear hearing aids you would know what your talking about. Aids are Not a "poor supplement" for the hearing one has. They increase the tone that one has a problem hearing and levels the playing field. They are designed for NORMAL sounds, and being around tractors, etc. is not a normal sound. It is amplified to the point of being unbearable. Even an air compressor running if I walk by is way to loud. That is why my remote has an OFF setting and the aids become ear plugs, basically. Don' need any muffs, etc.
Any good hearing aid has a high limit cutoff so the hearing aid by design will not amplify noise to cause hearing damage. It sounds like the high cutoff in your hearing aids are not working or not adjusted correctly.
Hearing aids are a necessary hearing supplement for many, but electronic devices do not replicate the natural hearing of the ear. While a necessary supplement hearing aids are also a necessary evil. Your hearing is damaged by excessive noise so you need a hearing aid to amplify the sounds in the damaged range. The amplified sounds over time cause more damage in the hearing range that is already damaged.
No I don’t wear hearing aids yet, but after 37 years in power plant I am getting close. I have done the research and know I want to delay the inevitable as long as possible. In the mean time I wear hearing protection with a minimum NRR of 28 dB and will continue to use hearing protection when I make the move to hearing aids.
