Abstract
A test system includes an instrumented mannequin head coupled to measurement and control circuits. The instrumented head can be located at a test site. Audio from a communications system emitted by a helmet placed on the instrumented head can be evaluated and the system repaired or adjusted for improved performance at the test site.
Claims24
A sound evaluating system comprising:
- a mannequin which carries first and second spaced apart microphones, and an audio output transducer spaced apart from the microphones but therebetween;
- and
- control circuits coupled to the microphones and transducer, the control circuits are responsive to audio signals received at the microphones and provide an audio output to be emitted by the transducer.
A method of testing performance of a device such as a headset or helmet comprising:
- establishing at least one audio receiving location and at least one output audio emitting location;
- positioning a device to be tested adjacent to the locations;
- emitting test audio from the device;
- sensing the test audio at the audio receiving location;
- converting the test audio to a first electrical signal;
- transmitting a representation of the electrical signal to an evaluation location;
- emitting selected audio at the output audio emitting location;
- sensing the emitted selected audio at the device;
- converting the emitted selected audio to a second electrical signal;
- and
- transmitting a representation of the second electrical signal to the evaluation location.
