High frequency hearing test: What hearing aids are best?

I started a discussion of this the other day. It has tips that I think you will find helpful. Good luck!

@guizar, California law mandates a 30-day trial period. Costco is usually pretty good with hearing aids, and many stores have audiologists or licensed hearing aid dispensers on staff. Is it possible you misunderstood what he said?

@golden418. If you have a chapter of the Hearing Loss Association of America in your area, both you and your wife would find others with similar experiences and probably also some solutions. Check the website, hearingloss.org/chapters, to find a chapter. Also, my 2013 book "Shouting Won't Help: Why I and 50 Million Other Americans Can't Hear You," available on Amazon and elsewhere, described in detail the difficulties I and my friends and family had in understanding the impact of my progressive severe hearing loss. In the book I share not only my own experience but those of others who have also wrestled with adjustment to hearing loss. A forum like this one (Mayo Connect) can also help, though a face to face gathering at an HLAA or ALDA (Association of Late-Deafened Adults) meeting can be transforming.

He told me I can use it inside the store for 30 minutes and that is it period. I did some search that for my type hearing loss there is only some hearing aids that compress the high frequency sounds to lower frequency to hear the words but it will not sounds same and have to have therapy to train me to recognize the sound of high frequency letter such as S, F for a few weeks and some hearing aids dispensers said they can help with %50 improvement which I don't believe them. I was hoping to hear from someone has same type hearing loss to see what they are done for hearing improvement.

Assuming that this device is defined as a "hearing aid" there should be a State Law giving you a Trial Period. Most states have a mandatory trial period for a hearing aid purchase. You need to check to see if your state has one...

I'm not sure of the rest of this story, but find it alarming that someone is being told they are not allowed to have a trial period when purchasing a hearing device. Are you referring to something called a Personal Sound Amplifying Product (PSAP)? PSAPs have been available by mail order and in some shops for a long time. They are NOT hearing aids per se, and all they do is amplify sound. You are talking about sound compression which seems to indicate you're trying real hearing aids....or something that is being falsely advertised as a hearing aid. It simply isn't possible for the brain to adjust to a 30 minute in-store experiment. Go to a reputable audiologist who has AuD behind their name. That stands for a doctorate degree in the field of audiology. Most of us with noise induced hearing loss, which is the most common type of sensorineural HL, have high frequency loss. What you describe having is not unusual. Further, most high quality hearing instruments from several respectable manufacturers, have the capabilities you will need. Not sure how to tell you this other than to say that it sure sounds like you're being fed a lot of baloney (for lack of a better word). At the very least, find some people who use hearing aids and talk to them. Find out who their providers are. Don't be taken advantage of. Find an HLAA chapter in your state and connect with the PEOPLE there. Good Luck!

No referring to hearing aids called ReSound LiNX 3D cost $2900.

We are all baffled by the comments you've made about not getting a trial period. I don't know of a single state that doesn't require a minimum 30 day trial period, but I could be wrong. Where do you live? Don't by anything you cannot try in regular situations for at least a month. ReSound LINX 3D aids are quality hearing instruments, but it sounds like you are dealing with a very unscrupulous provider. Go elsewhere. Did this provider inform you about telecoils? Another blank in the script if they did not. Go elsewhere.
