  • Exhaust Silencers

    Industrial Acoustics Company

    IAC Acoustics is able to offer a complete range of exhaust silencers for both diesel and gas engines. Our range of silencers utilise reactive and absorptive principles and in some cases, a combination of the two to provide the most effective sound reduction levels.

  • Tapping Machine

    STM-1 - ECO-TECH

    Tapping Machine Type STM-1 is intended for measurements of acoustic insulation of ceiling in buildings. The unit fulfils Annex A of ISO 140-6/7. These parts of the standard require a tapping machine as a sound source for impact noise measurements. Type STM-1 is available with an optional remote control.

  • Audio Oscillator & Sweep Generator

    SweepGen - David Taylor

    SweepGen turns a PC into an Audio Oscillator and Sweep Generator which can be used for testing audio or educational purposes. In conjunction with audio test instruments, you can make frequency response plots. SweepGen uses the sound card in your PC to produce sine waves that are mathematically correct almost to CD quality, indeed it's more likely that the quality of your PC sound card will be the limiting factor rather than the code in SweepGen.

  • Online Tone Generators

    Dr. Ir. Stéphane Pigeon

    Output of our tone generators will be downloaded straight to your computer as a .wav file. In other words, our waveform generators will generate high quality sound files, but won't play them online, ensuring the highest sound quality one can obtain on a computer. Single Frequency: Sine Tone Generator, Square Tone Generator, Sawtooth Tone Generator, Triangle Tone Generator. Dual Frequency: Dual Sine Tone Generator (IMD Test). Variable Frequency (sweep) Audio Signal Generators: Sweep Tone (Chirp) Generator.

  • Acoustic Condenser Microphones & Preamplifiers

    PCB Piezotronics, Inc.

    When you need a microphone for product tests such as sound power, sound quality, noise source location, there's no need to compromise quality and performance for a great price. With 100% of its microphone manufacturing in-house, PCB Piezotronics provides condenser, modern prepolarized, traditional externally polarized, array, probe, low-profile surface and other specialty purpose microphones, preamplifiers and accessories.

    The hand-held XL2 Analyzer is a powerful Sound Level Meter, a professional Acoustic Analyzer, a precision Audio Analyzer and a comprehensive Vibration Meter in one instrument. Easy operation and countless applications distinguish this quality Swiss product.

  • Pink and White Noise Generators

    Gold Line

    White noise is shaped and filtered to make Pink noise which is an essential tool for running many tests on sound systems. Pink noise provides equal energy per octave allowing the Adjustment of equipment drive levels with constant Hz bandwidth analyzers such as Gold Line RTAs. The spectrum of pink noise approximates that of much music which makes it an excellent test signal for sound systems. Many people select pink noise in place of white noise since higher levels of white noise can burn out tweeters. The model GLPN, when time averaged, produces levels of plus or minus 1 dB making it an excellent standard for "FLAT" response. With a good pink noise source the user can adjust equalization and speaker crossover points and balance systems. Pink noise is also useful for sound masking systems and to provide greater privacy. It has also been utilized to help employees with Tinnitus.

  • The Leading Measurement System for the Analysis of Porous Materials

    ELWIS - Autoneum Holding AG

    ELWIS (Evaluation of Light Weight Impedance System) offers a full and rapid characterization of porous materials based on the analysis of a single sample. The ELWIS system consists of the ELWIS-A and ELWIS-S components which can be used independently from each other although both applications are needed for a complete material simulation.ELWIS-A measures acoustic parameters that are needed to evaluate the acoustic performance of sound insulation and sound-absorbing multi-layer materials. An additional impedance tube for absorption measurements at higher frequencies is available for ELWIS-A.ELWIS-S measures structural parameters that are needed to simulate the dynamic and acoustic behavior of sound packages in the medium to low frequency range (including the "Poisson Ratio" for foam materials).ELWIS is very easy to operate: Thanks to its user-friendly software, the system can also be used to obtain reliable results by users with only limited experience in the characterization of porous materials.
