Mobile Sound Ranging Array
MSRA
In a peer to peer conflict, weapon location radars used for counter battery purposes will be extremely vulnerable.With aerial/satellite based surveillance available for the opponent, radars will be seen. With electronic warfare means being omnipresent, radars will be triangulated and jammed. There is an urgent need for 24/7 persistent surveillance with (preferably) passive sensors. With mobility being the key for survival on the battlefield, rapid re-deployable, or even truly mobile sensor capabilities are required. Therefore, the traditional sheer sound pressure based sound ranging capability becomes obsolete, as the triangular footprint of the sensor nodes is too large to be installed on a manned, or unmanned platform. With the trend towards longer ranges and “shoot and scoot” drills, the concept of capturing the muzzle blast noise becomes questionable, as the speed of sound is too slow to provide timely localizations.

Sound Level Indicators
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.An important attribute to consider when searching for a suitable sound level meter is its type or class. The type or class of a sound level meter defines the device's accuracy as per American National Standards Institute (ANSI) or International Electrotechnical Commission (IEC) guidelines. Typically, "type" is the grade according to the ANSI S1.4 standard, whereas "class" is the grade according to the IEC 61672 standard. There are two types or classes assigned to sound level meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 sound level meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.

Non-Intrusive voice Quality Analyzer
NIQA
The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).
