Microphone is a high quality, instrument-grade transducer with 100 times better low-level sensitivity than standard electret microphones. Hear a whisper at 40’. Low frequencies are key to identifying vehicle signatures. This microphone’s response is flat to below one cycle-per-second. Industry standard electret microphones use plastic diaphragms that don’t respond well to environmental change. Advantacs’s microphone diaphragm is constructed from a thin layer of titanium making the transducer immune to temperature and humidity effects. It also has over 120 dB of dynamic range so that even the quietest whisper won’t be saturated by wind |
