Resound question

I am in the trial period of a Resound aid from Cosco. Is it normal to touch the rear mic area and not hear any noise like when the front mic area is touched? I get an evasive answer from the tech at Cosc.

In omnidirectional mode maybe.

Don’t worry about how the darned things do their stuff!

I hear something when I touch either mic but I also hear that same scraping noise no matter where I touch the body of the aid.

Don, I understand what you said. But to be more specific I get noise most everywhere I touch except at the rear mic.

I just tried mine again and I see what you are talking about, the scratchy sound is quieter right on the rear mic holes than on any other spot. It must be normal if both of ours do the same thing?

Hal another consideration I have had resound “pixel” for 2 years with 4 breaks. at 300$ repair each = 1200$ pixel line no longer made.

I am in a controlled environment. Only moisture I deal with is sweat.

I encourage you to understand how it works in that its the only way to know if its working right or not. or if its going to be an issue down the line.

I am not familiar with your model specifically are any of the holes against the scalp side?? if so your going to have some serious issues with sweat funneling in to the aid.

think of a plunger pushing moisture in to the aid.

hmm manufactures don’t want you to make informed decisions.

curious though does costco have an Official audiology department? When I hear costco I think of the super discount website online. http://www.costco.com/

checked out the site, I would be leery of the training level of said staff, Usually audiology departments will advertise that staff are “trained professionals” with some level of college degrees to back said training up.

distribution wholesalers main focus is to sell, your hearing is second to that.

so if they are NOT being completely up front with you about “questions” then I would consider that “against” “the aids” and “costco”.

people that have your best interest at heart is going to be completely forthcoming. If they don’t know they will admit it. If they don’t have the answers, they will find out for you well before the trial period is up.

Personally if I was in your shoes I would be looking for different aids and Audiologist.

When they are not answering questions, that screams, they are hiding something. honest business people do not need to hide things.

I am in a controlled environment I certainly hope so!!

environmentally controlled in this case

Taken out of context once again. you have a bad habit of doing that to my post this is at least the third one you have done this too

Quote from my post:“I am in a controlled environment. Only moisture I deal with is sweat.”

the second sentence, I was implying about moisture exposure to the first.

non controlled environment in this case would be out in the rain, where rain could damage the aids. Or out in tropical weather that could cause excessive sweating.

really getting annoying to have posts of mine twisted out of context to say something that I never actually said.

are any of the holes against the scalp side I have never seen a HA with the mic’s on the scalp side do you have a link?

does costco have an Official audiology department yes, about every 3rd or 4th post on this forum talks but Costco hearing aids. http://shop.costco.com/In-The-Warehouse/Hearing-Aid-Center.aspx

My comments in bold.

You admit that you don’t know anything about Costco Hearing center but you don’t mind saying they are a bad place to buy hearing aids. Great advice, well informed and a complete waste of time. Thanks, Discount web site really?
One year with Resound Future and thay have changed my life all for around 3200.
Try reading and researching a product before you start slandering a company.

Hal:
My wife has the Resound Future from Costco. They too make a sound when touching the body of the aid. I believe this is normal. My Kirkland Signatures do the same when I touch the body of the aid. So far we’ve had a great experience with Costco. As far a the tech being evasive maybe you misread the person. In any event the HA’s come with a 90 day trail, 3 year warranty & 2 year warranty against loss/damage both with no-deductible so if the issue you’re experiencing is actually a problem it can be corrected. If the HA’s help to improve your hearing I don’t believe you will get a better price point for the quality.

All the best to you in your trial use.

Don, thank-you. Your replies were very helpful. I agree ,things must be OK. Hal

Without a doubt! I couldn’t of said it better myself! All Costco Hearing Centers are employed with trained professionals depending in which Province or State you live in. There are groups and associations that prevent sales from non-professionals.

A hearing aid is just as good as there fitter. Regardless of status of Audiologist, Registered Hearing Aid Practitioner, or Hearing Instrument Specialist.

Where I’m from an Audiologist can diagnose and fit children, whereas a RHAP and/or HIS cannot. All tests are done exactly the same, finding the clients true threshold speech discrimination scores etc.

Anytime you touch or rub the body of any hearing aid, you will hear an amplified sound. Essentially, it is a micro speaker and microphone system. My suggestion… AVOID TOUCHING IT OR DON’T TOUCH IT AT ALL. LOL =)

From my understanding the front mic’s (closest to your receiver) are directional and the rear are omni. Now it could all depend how the hearing aids are programmed as well. There is the Focus ear system and Basic and soft switching. The front mic will always be more active because those microphones are the ones that look for speech. On a sound wave speech is more dynamic vs noise which is less dynamic. The technology that allows that front microphone to take speech and amplify and resonate throuhg the canal and eardrum has been very good since being introduced in the digital circuit since they aim ahead of the hearing aid user. Meaning, ideally, hearing aid users should always look and face the speaker during conversation because of the design of it, so you’re front microphones are always scanning ahead looking for speech, taking it, and amplifying it. Your back microphones are more for environmental noises to make you aware of whats behing you and around.

I hope this helps

Your understanding of the mic properties would be a little out of date. Rear mics don’t point backwards and front mics don’t point forwards.

Training from Resound 2011 is a bit out of date I guess. Just information I was trained with, could you perhaps give me a better understanding of front and rear mic’s. I would appreciate it. Thanks

Each mic is omnidirectional, but it’s the addition or subtraction of the signal from the pressure wave hitting the mic tubes at a given distance apart combined with an electronic time delay that defines the properties of he mic array.

If the delay is exactly the distance between the mics, you get a forward facing cardiod pattern, halve the delay or double it and you make a hyper-cardiod/figure 8 pattern.

There is no ‘forward’ or ‘rear’ sound designation as such. In some older instruments a twin ported ‘directional’ mic was used in conjunction with a single ported ‘omni-directional’ one, to achieve a switchable forward directional pattern.

go to the link I placed in thread of the “design flaws on the rise”. The link is to the model “Pixel”

It uses a universal case for both left and right ears. That has 4 mic holes on the sides of the casing (2 on either side). The mic is actually in the center with openings facing out the sides. It was a really BAD DESIGN. 2 holes ALWAYS sat against the scalp when worn properly.

I just went to resound site it looks like they no longer use side mic holes because side mic holes requires two separate factory lines to assemble when properly implemented. mic holes only facing out which requires right and left casing thus 2 factory lines. Thus double the expense of making properly.

regarding touching the case anywhere and generating sound:

unless the mic is physically separated or has vibration dampening to separate it from the aid casing, it will always make a sound when scratching the casing anywhere. It does it through “vibration transfer” to mic. Its just like when you rub the head of a loud speaker right over the mic. Vibration and sound waves are the same.

I can scratch my earlobe with the aid in and still hear it. if the vibration transfers through to the aids casing.
