Information
The Artificial Voice Type 4219 is a complete redesign of the
Artificial Mouth Type 4216. It is intended for use in
laboratories and quality production control, when a well
defined sound source is required, and when it is more
convenient to use an artificial source rather than the human
voice.
The Artificial Voice produces a sound field similar to the
sound field from a human mouth, and also covers the
frequency and pressure ranges normally produced by the human
voice.
it is equipped with a built-in condenser microphoneand
preamplifier, which can be used with the compressor circuit
of a B & K Beat Frequency Oscillator to maintain a constant
sound pressure at the orifice.
The characteristics of the voice make it suitable for
general acoustic work, and telephone measurements.
