Acoustic Analysis From noise reduction in trains, planes and cars to detecting, classifying and tracking battlefield targets such as tanks, our acoustic analysis software bundle provides accurate, stable acoustic measurement and analysis. It incorporates our innovative Nth Octave processor that processes CATS and DATX data files to provide single-channel, octave-fraction-based spectral analysis in sound pressure level (SPL) and power spectral density (PSD) form as well as our acoustic intensity analyzer that performs a classical, two-microphone, fractional-octave-based, or narrowband calculation to provide direction-sensitive spectral analysis.

Iasys - Acoustic Analyzer Iasys (pronounced; I assist) is a fuzzy logic based audio analyzer. An acoustic analyzer for amplitude, phase and frequency, completely self contained and portable. It gathers and processes acoustical information and delivers answers in real-time. Answers that can be addressed with the tools available to all audio professionals. Iasys does not require the knowledge of electro-acoustics, electronics or physics previously needed to decipher frequency/time domain analyzers.

Acoustic Analyzer Occupant comfort is a goal for all HVAC designers and sound (or noise) is a key parameter in measuring comfort. For most applications, it is the HVAC designer that is tasked with creating a comfortable acoustic environment to minimize background sound from the HVAC system. Acoustic Analyzer software is a DesignTool developed by McQuay to help designers estimate the sound of HVAC equipment in a space or outside a building.

213A - Acoustic Tester The Acoustic Tester is a plugin module to Telecom Tester 213. With Artificial Head 214 (or Brüel & Kjær) it measures the acoustic parameters of a handset. A sweep of up to 46 frequencies gives the frequency response curves for the transmitter, receiver and side tone. A pass/fail test can be made against pre-set limits for the mask (upper and lower limit of the frequency response) as well as for the calculated Loudness Rating or OREM values.

Acoustic Enclosures Acoustic isolation requires carefully designed panel elements. One major factor for maximum isolation is a high weight-to-area ratio. Unfortunately, this generates large handling forces during opening and closing of the front door. IDE has integrated a servo-pneumatic mechanism to solve this problem.

Differential Acoustic Emission Sensors Our differential sensors are identical to our general purpose sensors in physical, electrical and response characteristics, except that two signal leads (instead of one as for general purpose sensors) are brought out to attach to a differential pre-amplifier. By using a differential preamplifier, common mode noise is eliminated, resulting in a lower noise output from the preamplifier, and a higher electrical noise rejection in difficult and noisy environments. Noise improvements in the range of 2dB or higher can be expected using a differential sensor and preamplifier over a single ended general purpose sensor.
