QUESTIONS & ANSWERS
Ask BCM a Question-
Will your D200 detect a signal from a high frequency speaker that will reproduce frequencies in the audio range of l0Khz up to 50KhZ. Specifically in the 25 to 40 Khz range. These higher frequencies can be heard by dogs as you know. If the D200 will not do this can you recommend a unit that will. I have a serious problem with HF noise generated by a Signal Generator such as a HP Model 200AB Audio Oscillator. l Hope you can help me. Regards, Mike Day
Hello Mike - Yes the D200 will easily detect your signals of interest. As a tunable heterodyne, you would tune it yourself to "zero in" on the sound, and then the D200 will be displaying the tuned frequency. Some other options are the BatScanner which reports the frequency of the loudest ultrasound present. But you might be most interested in the the USB microphones... the Pettersson M500, u256, and u384 run on included software BatSound Touch that would let you monitor sound in real time on a live sonogram. Those devices are compatible with other sound apps such as Audiacity, and smartphone apps like BatRecorder. All of which provide live sonograms so as your sound changes, you can see it in realtime. The Binary Acoustics AR125 is expensive with excellent quality and may be more than you need. Thanks-JC
