The Infiltec Model INFRA20 infrasound monitor is designed to record. Display and analyze infrasound below the human hearing range in the 0.05 Hz to 20 ... moreHz range. Infrasound is produced by wind turbines, helicopters, meteors, avalanches, volcanoes, large animals like elephants, etc. The INFRA20 is designed to provide infrasound monitoring for lab, home, school and field use in a compact, portable, and rugged package that is less expensive and easier to use than conventional designs. The INFRA20 does not require any power supply or assembly or enclosure or adustment; including alignment, damping, zeroing, etc. The INFRA20 works with the standard AmaSeis Windows based software, and with the new jAmaSeis software for Windows, Linux and Mac OS. For laboratory. Field, school, office, or home use to record and analyze infrasound. This infrasound monitor comes with a 15 ft(4m) serial cable, 15 ft(4m) of 1/8 inch ID plastic tubing, a USB-Serial adapter, and a CD contianing Windows software and software manual. Detects infrasound in the 0.05 Hz to 20 Hz band that is generally inaudible to the human ear. Applications include monitoring wind turbines. Machinery noise, building noise, elephants and other large animals, meteors, avalanches, volcanoes, earthquakes, cryptozoology studies of big foot and sasquatch, and paranormal investigations. Requires an attached PC to log and display infrasound data. But other programs can run on PC while the infrasound data logging program is running. Works with Windows XP and above. The seismic data logging and analysis program AmaSeis is supplied on CD. Also runs with the new jAmaseis seismic software that runs on Windows, Linux and MAC OS. The INFRA20 is not very sensitive to vibration or orientation. But it is very sensitive to temperature changes or altitude changes. Serial extension cables up to 100 ft can be used to connect it to the data logging PC. The infrasound sensor is a differential pressure sensor with 1/8 inch ID tubing connection that is located on the side of the box that

ALL FUNDS FOR SHIPPING AND FOR THE ITEM WILL NEED TO BE DEPOSITED IN MY ACCOUNT BEFORE SHIPMENT AND TRACKING INFORMATION WILL BE PROVIDED. NO EXCEPTIONS WITHOUT PRIOR AGREEMENT WITH ME THE SELLER. Audio Phase Detector* Designed and Built by Charles Kitchin of Analog Devices Norwood. MA. Audio Phase Detector For the owners of a modest stereo system utilizing one speaker per channel. Phasing the speakers is a relatively easy task. By connecting the speakers by polarity dots or switching the leads from one speaker and listening for the most solid bass response and best stereo centering, proper phasing is accomplished. However. If more than one amplifier is used such as in biamp and triamp systems, phasing can become a horror show. Unless the amplifiers are identical(i.e.the same phase shift in each) wiring up the speakers by polarity will not work. The problem is compounded by the electronic crossover which may, or may not, have the bass, midrange, and/or treble outputs in phase with another. Also microphones and audio lines are difficult to phase correctly. Device Description. A simple and inexpensive solution to this problem is to send a coded signal through the system. It is picked up on a portable receiver which can listen to each speaker individually and indicate its phase relative to the other speakers in the system. Such a device is the audio phase detector. The coded signal is a sawtooth waveform generated by an integrated circuit voltage to frequency converter(a voltage-controlled oscillator) The Analog Devices AD537. A sawtooth waveform is connected to the line input jack of an amplifier, amplified, and the speakers will produce the waveform into a sound wave picked up by a microphone on the receiver. The air mass between speaker and receiver acts like a capacitor and differentiat

Bruel& Kjaer Type 4152 Artificial Ear- Two units will be included as will all the accessories that are pictured in the photographs. They appear to be in reasonably good condition for their age.

No microphone capsules or preamplifiers are included in this sale. Both manuals. Assorted cables, and misc parts shown will be included. Please feel free to ask any additional questions you may have.

This Bruel& Kjaer equipment is an unknown model. It appears to be an ear simulator or mouth simulator. It's likely missing pieces and includes extras. The microphone has a four pin connector and no markings. It doesn't look like a B&K microphone to me. And is untested. The microphone cable is flattened in one spot, visible in the photos if you zoom in.
