  • Signal Splitter

    G Systems, l.p.

    The Dynamic Signal Buffered Splitter protects sound and vibration sensor acquisitions from the unwanted effects of a parallel troubleshooting or diagnostic instruments. G Systems Dynamic Signal Buffered Splitter provides buffered and unbuffered outputs connected to the same signal input. Up to 16 sensors, typically accelerometers, proximity probes, microphones, and pressure transducers, may be connected to the 16 signal inputs.

  • Power Line Meter

    Alpha Lab, Inc.

    The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

  • Psyacoustic Test System

    Jumho Electric Corporation

    Psychoacoustics is the science of the relationship between physical quantities of sound and subjective hearing impressions. To examine these relationships, physical parameters, such as loudness, sharpness, roughness, fluctuation strength, are mapped to hearing-related parameters. Unlike the physical quantities, these hearing-related quantities – also referred to as psychoacoustic parameters – provide a linear representation of human hearing perception. The psychoacoustic test system, with interactive interface and user-friendly operations, analyzes psychoacoustic parameters effectively and conforms to the international standard ISO 532 Part B.

  • Acoustic Testing & Measurement Software

    Smaart - Rational Acoustics LLC

    Smaart is an analyzer – A dual-channel, FFT-based software platform we use in our work as audio engineers to view the frequency content of signals or measure the response of our electrical and electro-acoustic systems. Much like medical instrumentation for doctors, this tool helps us examine our sound systems in detail and diagnose and solve problems. Because Smaart is a software product, it provides the power of extremely powerful hardware-based analyzers in a package that is affordable by an average audio professional.

  • A Global Standard for Acoustic Absorption Measurements

    Alpha Cabin - Autoneum Holding AG

    The Alpha Cabin has been especially designed for the measurement of acoustic absorption properties of materials and components used for the noise insulation of vehicles. The Alpha Cabin is significantly smaller than normal reverberation rooms and therefore ideally suited to use within limited space capacities. The acoustic absorption of the Alpha Cabin itself is also very low: Thanks to the high level of sound insulation, background noise in the frequency range of interest is kept to a minimum.
