Voice Enhancement Techniques of the ChairSpeaker
As some of you know by now, starting this month KARE, LLC will now be producing the ChairSpeaker locally, here in the US. So we wanted to take a moment to go behind-the-scenes a little bit and explain how some of our features work.
One of the ways we manipulate sounds waves to make it clearer to understand what is being said is through our selectable Voice Enhancement feature.
This is created by an electronic circuit that amplifies the voice frequencies and reduces frequencies outside of the voice range. It essentially changes the voice range depending on their hearing preference. Our transmitter has two options for voice enhancement depending on what you need.
One of the voice-enhancement options allows for Low Frequency Hearing Enhancement (hearing loss of frequencies of 2,000 Hz or lower), while the other option offers High Frequency Hearing Enhancement (hearing loss of frequencies from 2,000 Hz to 8,000 Hz).
This is all done by having an enclosed geometrical shaped speaker housing, made out of a special plastic to resonate voices. The illustration above helps break down how all of these components come together.
The voice tuned speakers concentrate power on the human voice range, while the voice enhancing rubber eliminates the tinny sound produced by some other voice enhancing systems making our sound richer, fuller and more vibrant. The voice enhancing ridges help eliminate unwanted vibrations that may lead to muffled voices.
When you put all of these components and features together, what you get is the foundation of the ChairSpeaker system.
