Thin tube vs. thick

I am curious and new at this, but I assumed that thin tubes are newer, more advanced, and state of the art. Yet I see a lot of pictures of very expensive HA which look as though they use only thick tubes and a few basic models that use either.

I am sure I am missing some basic knowledge here. Thanks

Assuming fixed hearing aid setting, reducing the inner diameter of the tube will both shift the resonant peaks in the frequency response and decrease the high frequency response. With that being said, here are two links that provide more info regarding Phonak Power Slim Tubes.

Thanks. There is more going on here than just looks. Good to know.

chas, I’m new at this too. Are you thinking of the tubes in pictures like this one?


I think the tube in these aids is actually tucked behind the ear out of sight, and I assume a thinner tube would lead to the ear canal. But I’m guessing.

You don’t say why the thick/thin means something for your purchase. Most are opting for RIC units that have a very thin wire going to the receiver(speaker) inside the canal. Tube these days seem for those in the realm of a specific, profound loss. With the RIC types you enjoy a smaller behind the ear product. And even many that formerly need BTE (tubes) have more powerful RIC units that address some of the reason they weren’t used in the past.

Daisymae, I cannot tell from your link. But I am thinking of one like the Phonak Naida S. And my question has nothing to do with me. When I look into any subject I just like to know as much as I can. And I totally forgot about the RIC units. Told you, new at this.
