Jeff thanx man! I am aware of this method of the use of morse code by deafblind persons.
What I'm just wondering about is that I may need more detail than would be available in a morse code system. Also with the kind of music I listen to you need bass frequencies a whoofer might not be able to provide? This is actually fascinating research I think. -----Original Message----- From: Pc-audio [mailto:pc-audio-boun...@pc-audio.org] On Behalf Of Geoff Eden Sent: 28 September 2015 12:38 AM To: PC Audio Discussion List Subject: Re: feeling bass frequencies Cognitive transference, it's entirely possible that with use your brain may kick in the bass for you. A long time ago there was a deaf blind ham operator in central Canada who used the Morris code for communication. A gentleman at the national research Council built a speaker box whose speaker cone he filled with Styrofoam, and then topped with plastic for protection as this person's hand would be on the speaker a great deal. This person worked the radio for many years and most of her contacts never knew that she was deaf blind. Therefore I suggest a small Wolfer with major excursion capability and whose cone be filled with foam to provide you a flat surface. It too could be covered by a plastic film for protection. Small Wolfer's travel back and forth more distance, generally, than do large ones to get the air in the room moving. Hence, the term long excursion. It strikes me that some of those relatively inexpensive three point speaker systems for computers might have a ready made Wolfer box that you could adapt directly. I see them all over the place for around $100 or less. A computer repair store just may have a set of these speakers with the tweeter components not functioning, as it's rather common for their cables to break or deteriorate. Best of luck to you, and let us know if it works out. It's probably material for a research article.

If so the moderators must please let me know and I will request people to answer me off list. I have a very unique situation here. I have just had a second cochlear implant which resulted in my losing all frequencies below about 100 hz. This as many of you know results in you losing quite a deal of the lower bass sounds in music. I’m researching some way of now compensating for this. The only way I can think up is to use my tactile sense to feel the missing frequencies. Maybe the brain may put the signals of the audio and visual cortex together and create some kind of a whole. What I have done is to lightly rest my fingers onto the front of my reasonable quality sub whoofer. It is then indeed possible to do this. But it’s really not the most comfortable position to sit in also. Another thing – if you turn up the bass too much, the harmonics starts to distort the cochlear implants. So I’m wondering if someone has any thoughts on this rather unique challenge to share?
