Abstract
Abstract In an apparatus for voice training, on several points of a student's body measuring devices are provided, which are connected to optical display devices. At each of these measuring devices, a pressure sensor amplifier is connected with an analog multiplexer, and a sound-pressure measuring device is directly connected to the respective display device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
A voice-training apparatus comprising: a means for measuring dimensional changes on a flank of a human body, said means including a pressure sensor amplifier for flank pressure; a means for measuring dimensional changes on a thorax of said human body, said means including a pressure sensor amplifier for thorax pressure; a means for measuring dimensional changes on a head of said human body, said means including a pressure sensor amplifier for head resonance and for pressure at a tongue root; each of said means being attached to said respective flank, thorax and head of said human body. a respective optical display device for displaying values measured by each of said flank, thorax and head measuring means; an analog multiplexer receiving signals from each of said pressure sensor amplifiers and communicating with said respective optical display devices; and a squelch circuit selectively muting sound input depending upon pressure levels from said thorax and flank.
Claim 2
Dependent Claim
153 words
A voice-training apparatus comprising: a means for measuring dimensional changes on a flank of a human body, said means including a pressure sensor amplifier for flank pressure; a means for measuring dimensional changes on a thorax of said human body, said means including a pressure sensor amplifier for thorax pressure; a means for measuring dimensional changes on a head of said human body, said means including a pressure sensor amplifier for head resonance and for pressure at a tongue root; each of said means being attached to said respective flank, thorax and head of said human body. a respective optical display device for displaying values measured by each of said flank, thorax and head measuring means; an analog multiplexer receiving signals from each of said pressure sensor amplifiers and communicating with said respective optical display devices; and a squelch circuit selectively muting sound input depending upon pressure levels from said thorax and flank.
Claim 3
Dependent Claim
29 words
The apparatus according to claim 1 wherein said pressure sensor amplifier for head resonance includes an electret microphone and a nostril adapter with closed air column for both nostrils.
Claim 4
Dependent Claim
41 words
The apparatus according to claim 1 further comprising a storage device means for storing alternating-current pulses, said pulses being formed from said signals from each of said pressure sensor amplifiers received by said multiplexer and conveyed to said storage device means.
Claim 5
Dependent Claim
39 words
The apparatus according to claim 3 further comprising a sound-pressure measuring device which is a dynamic microphone and a play-back device, said microphone and play-back device being connected to said multiplexer, and said play-back device is a cassette recorder.
Claim 6
Dependent Claim
65 words
The apparatus according to claim 1 further comprising an automatic basic-pressure adjuster for each of said pressure sensor amplifiers, said automatic basic-pressure adjuster functioning to return said signals from each of said pressure sensor amplifiers that fall below a preset zero level back to said zero level, and an analog memory for recording peak values of said signals from each of said pressure sensor amplifiers.
Claim 7
Dependent Claim
65 words
The apparatus according to claim 1 wherein said means for measuring dimensional changes on said thorax and said flank are pressure sensors, said sensors being in pad form and connected via a hose to a common pressure sensor, said pads being supported on a belt fitted around said human body, and said thorax and said flank pressure sensor amplifiers being connected to said respective pads.
Claim 8
Dependent Claim
57 words
The apparatus according to claim 6 wherein said pressure sensor amplifiers function to provide a quick-acting correction to sensor signals from said pressure sensors as said sensor signals with respective to a time interval slightly drop and fall below a preset zero level, thereby ensuring that said belt has a basic pressure that always hovers around zero.
Claim 9
Dependent Claim
37 words
The apparatus according to claim 1 wherein said signals from each of said pressure sensor amplifiers to said analog multiplexer are successively converted in corresponding intervals to alternating-current pulse sets which are stored on a magnetic carrier.
