– Primary Test: The easiest sound source to use with the Microphone is a tuning fork, but you may want to investigate a human voice or a whistle, electronic keyboards, and other musical instruments. Make sure the sound level is in the correct range to produce good wave patterns. If the sound is too loud, the wave pattern will be clipped at the top or bottom. Move the microphone further from the sound source, or turn down the volume of the sound.
An inexpensive keyboard set to the flute sound, without vibrato, is the best source; you can easily do both beats and pure tones of varying pitch.

– New Order Code: MCA-BTA

– Frequency range: approximately 100 Hz to 15 kHz. The maximum data-collection rate of the interface affects the maximum frequency you can effectively sample. With the LabPro or CBL 2, the maximum sound source is 5,000 Hz. With the CBL or ULI, the maximum sound source is 1,000 Hz.
– Calibrate? No. The sensor is set to the stored calibration before shipping.
