Yes !
Repeated & Prolonged exposure to sounds of that magnitude WILL cause you enough hearing loss to prevent you from UNDERSTANDING your children and grandchildren when they speak to you. Think about it!
Noise Induced Hearing Loss occurs slowly over a working or playing lifetime, and affects the high frequencies of your hearing sensitivity. The sounds in the English language that help us understand one word from another word are high frequency sounds. With a high frequency hearing loss, you hear someone speaking, but, you do not understand one word from another....
In my 20+ years as a military audiologist, I can't begin to convey to you the number of men who have come to my clinic saying their wife is leaving them because they can't hear.... Sounds unlikely, yet, for a large number of people the inability to communicate with a significant other is certain death for their spousal and working relationships. And, hearing loss can contribute mightily to such a communication problems!
I know I sound trite and judgemental, but I encourage you to do a smart thing for yourself and avoid loud sounds for any extended period of time.
If you can't avoid loud sounds, wear hearing protection.
Hearing protectors around your neck, in your pocket or in your tool box do not help
You need to wear hearing protection consistantly and properly.
I'm retired now, but, if you have any questions about noise, hearing or personal hearing protection, just ask, I'm happy to dust off my soap box and make a speech just about any time.
If I don't know the answer, I know world class experts who do....
Good luck with your exhaust

Low frequency sounds....
arista5,
I'm not sure where you're aiming your question. I have several speeches about low frequency sounds, but don't know which one you might be interested in
I'll stab in the dark for you anyway:
Low frequency hearing sensitivity is usually not affected much until decades into the disease process of Noise Induced Hearing Loss. This is due primarily to the anatomy and physiology of the inner ear, and is too complicated for an explanation here. Although, there are difinite individual differences.
Energy in sounds of the English language is more intense (louder) in the low frequency "vowel" sounds and much less intense (quieter) in the higher frequency "sibilant" sounds.
So, we have more difficulty hearing high frequency sounds, even with normal hearing sensitivity. The vowel sounds carry better because they are louder to start with and also because the wave
length of the vowel sound bounces off environmental objects
and carries farther than the short wavelengths of the high frequency sounds.
The high frequency sounds of English are quieter, are easily masked by environmental sounds, and do not carry very far.
So, even if you hear perfectly, you can miss the higher frequency sounds that help you discriminate one word from another.
Bottom line: With Noise Induced Hearing Loss you will hear the vowel sounds pretty well, but will not hear the other sounds that allow a you to discriminate between one word and another.
Hence, my original statement: Repeated & Prolonged exposure to sounds of that magnitude WILL cause you enough hearing loss to prevent you from UNDERSTANDING your Children and Grandchildren when they speak to you. Think about it!
If you are already having difficulty understanding people, do this:
1) Watch their face, your brain will fill in many of the sounds you do not hear, and
2) Teach your friends and family to get your attention BEFORE they begin to speak to you, and
3) Repeat what you think they said so they will only have to repeat what you missed....
This was a "shotgun" approach to answering your question, does it answer the question you had in your mind when you asked "what about low frequency sounds?" If not, ask away, my rates re pretty cheap on this forum

Thanks again Lee
I try to do most of the things you described and they usually make a big improvement but phone conversations can be very frustrating to both parties
i have reasonable hearing loss from working on and around jet engines in school and at work we have very large AC units in my main network data center which are loud as hell and also being an avid heavy metal fan and all around loud music fan (i love bass...especially bad for me??)
Thanks for your advice and help

I'm happy to hear you are interested in preserving what hearing you have remaining.....
Hearing loss from the exposures you describe above is very gradual and very predictable, and, very real.
The thing you MUST realize is that Noise Induced Hearing Loss is CUMULATIVE, it never stops if you are still exposed to loud sounds.
That is why a person in your situation should limit their exposure to loud sources and wear hearing protection when you can't (like A/C units and jet engines -heavy metal too
As far as talking on the telephone. There are amplified units for use at home (Target has always carried one or two models.) There are also portable amplifiers you can carry with you that fit right over the reciever when you are not at home. There are also TTY units but they are prolly outdated by e-mail and chat programs. The video phone may develop to a point that it could give you some of the visual cues you use in person (lip reading.)
The biggest single thing that people can do to communicate to a person with hearing impairment is to SLOW DOWN! Speak slowly and people with hearing loss can get more from your speech. (Being a political junkie, I'm holding back a good poke at some voter's critical thinking skills, relative to speaking slowly )
My best to you
