DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an apparatus for voice-training with several measuring devices provided at several points on a student's body, namely on the flanks and thorax for measuring the dimensional changes and on the skull and connected to optical display devices.
THE RELATED ART
Apparatuse for monitoring, particularly for self-training in speech- and singing techniques are already known, since adult speakers or singers are very often not in the position to naturally coordinate their sound emission, i.e. each sound delivery, such as speaking, singing, and the like with breathing techniques, without the benefit of training, such as is the case in animals or particularly in small children. With the known apparatuses, points on the body of a speaker or singer are connected to optical display devices via measuring devices, and the display takes place through lighting on determined points of a board. However, it has been found that the heretofore-known apparatuses could stand improvement, and that primarily a new distribution of the measuring points on the body could be appropriate.
SUMMARY OF THE INVENTION
Now, according to the invention, it is proposed that a pressure sensor amplifier for the head resonance, a pressure sensor amplifier for the pressure at the root of the tongue, a pressure sensor amplifier for the thorax pressure and a pressure sensor amplifier for the flank pressure be directly connected to the corresponding display device, via an analog multiplexer and a sound-pressure measuring device, whereby the measuring device for the sound pressure is provided with a squelch circuit depending on the thorax- and flank pressure.
The present invention renders it possible not only to perform self-training, but also to offer to speech- and singing teachers the possibility to demonstrate to the student his own mistakes and to give instructions for their elimination. Due to the detection and recordal of the measured values at different points of the body, it is possible to constantly show the mistakes to the student, and it is also possible to identify improvements by superposition or through comparative displays.
BRIEF DESCRIPTION OF THE INVENTION
The present invention as well as its varied features, objectives and advantages are described with the aid of the examples shown in the drawing wherein:
FIG. 1 shows a basic circuit diagram of the apparatus of the invention, including the display device;
FIG. 2 shows a belt for measuring the thorax- or flank pressure;
FIG. 3 shows the sensor signals, wherein an automatic basic-pressure compensation has taken place;
FIG. 4 represents a pressure sensor amplifier; and
FIG. 5 represents a sectional view of a face illustrating nostril adapter and tongue root sensor.
DETAILED DISCUSSION
FIG. 1, the arrangement of the invention is schematically illustrated. On the body of the student are affixed a pressure sensor S1 for measuring the tongue root pressure, a pressure sensor S2 for measuring the thorax pressure and a pressure sensor S3 for measuring the flank pressure each being connected over a pressure sensor amplifier 4 to the inputs of an analog-multiplexer system 5. The detection of the head resonance takes place over the electret microphone 6 and a nostril adapter 40 with closed air column, which is also connected to one input of the multiplexer system 5, via its own pressure sensor amplifier 7. Now a display board 8 is arranged, whereon display devices are provided. These display devices are associated with the individual measuring devices and are located on corresponding points of the display board 8. This way, there is one light bar 9 for the head resonance, one light bar 10 for the pressure at the tongue root 42, a divided light bar 11, 12 for the thorax pressure, a further divided light bar 13, 14 for the flank pressure and furthermore a selection unit 15. In order to measure the sound pressure, i.e. the voice, a dynamic microphone 16 is provided which is connected via a microphone amplifier 17 to a recording device, preferabl
