  • Decoders

    LokProgrammer - Electronic Solutions ULM GmbH & Co. KG

    You want to listen to the sound spectrum of your favourite loco, or the special sound of that loco around the corner in the yard – on your model railroad? No problem with ESU’s LokProgrammer!

  • Acoustic Analysis

    M+P International

    Noise is increasingly the subject of new regulations for the protection of human health and safety as well as for improving the environment in general. As well as sound levels, the perceived sound quality of products from washing machines to vehicles is often an important part of the customer buying decision so must be considered during product development. m+p Analyzer for noise and vibration measurement and analysis provides a full range of capability for these applications. Real-time fractional octave filters satisfy all acoustic applications from simple sound pressure, sound power for equipment legislative requirements, intensity mapping to isolate sources to sound quality metrics for product refinement.

  • SPL Meter

    CM-80 - Galaxy Audio Inc.

    The CHECK MATE series SPL (Sound Pressure Level) meters, first introduced in early 2003, allow musicians, sound contractors, and others to measure SPL in decibels (dB). A decibel is defined as the unit for measuring relative loudness of a sound. We have expanded our line from one CHECK MATE SPL Meter to four products in the category. We have sold thousands of units to working musicians, DJs, police departments, sound contractors, racetracks, etc...

  • Analog Ultrasonic Inspection System

    ULTRAPROBE 100 - UE Systems Inc.

    The Ultraprobe senses high frequency sounds produced by operating equipment, leaks and electrical discharges. It electronically translates these signals by heterodyning them down into the audible range so that a user can hear these sounds through a headset and see them as intensity increments on the meter. Heterodyning works the same as a radio in that it accurately transforms the sounds so that they are easily recognized and understood.

  • System Design and Prediction Tool

    MAPP 3D - Meyer Sound Laboratories Inc.

    MAPP 3D, a free software application for macOS and Windows, is a powerful, multipurpose sound system design tool that delivers precise, high-resolution predictions of sound energy distribution in a three-dimensional sound field. From preproduction to post-show analysis, work faster and smarter with the ability to streamline processes and consolidate designs in one simple, accurate 3D model.

  • Noise Meters

    PCE Instruments

    Here you will find a full range with an industrial standard noise meter / sound meter to suit every requirement. With the portable noise meter you can carry out measurements quickly to gain control of a situation or to set the sound meter to take timed measurements. The noise meter is important for all industries, especially by using it as a mobile noise meter which is able to assess office stress levels or street noise levels. Often problems arise from noisy neighbors or if bars and restaurants are in residential areas and produce noise levels after 10 pm in excess of what local laws permit. A noise meter / sound meter will help here.We can assess which noise meter or sound meter you require in relation to the issue you have and the relating laws (requirements regarding a sound meter and a sound meter’s usage vary depending on the country). We also have noise meter microphone extension cords, tripods, sound meter calibrators and calibration certificates for most noise meter models.

  • Ultrasonic Leak Detector

    VPE - Superior Signal Company

    The Patented Superior AccuTrak VPE represents state-of-the-art technology for pinpointing leaks is air conditioning and refrigeration systems. AccuTrak is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called "heterodyning" it translates the sound to a lower frequency which your ear can interpret. AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. AccuTrak is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.

  • Acoustic Test Chambers


    Small Device Test Chambers are used for >Basic sound level measurement of small products and equipment >Pre-compliance testing of small products and equipment >End of line manufacturing test on small products and equipment Small Device Test Chambers provide acoustic isolation from outside sounds and/or reduce the sounds from the device under test radiating into the host

  • SPL Meters

    CM-170 - Galaxy Audio Inc.

    The CHECK MATE series SPL (Sound Pressure Level) meters, first introduced in early 2003, allow musicians, sound contractors, and others to measure SPL in decibels (dB). A decibel is defined as the unit for measuring relative loudness of a sound. We have expanded our line from one CHECK MATE SPL Meter to four products in the category.

  • Residual Intensity Calibrator

    CAL291 - Larson Davis, Inc.

    Under IEC and ANSI standards, a sound intensity measuring system consists of a two microphone sound intensity probe and a dual channel processor. The accuracy of the intensity measurement is strongly dependent upon the phase accuracy between the two measurement channels, including the microphones. Sound intensity measurement systems are classified into Class 1 or 2 based upon the pressure-residual-intensity index which is measured using a residual intensity testing device. For direct calibration or verification of the accuracy of a sound intensity measurement system, IEC 1043 and ANSI S1.9 call for the use of a sound intensity calibrator which delivers to the probe microphones the simulated intensity at a specified temperature, atmospheric pressure and nominal microphone separation.

  • Portable Calibration System

    HD9120 - Delta OHM S.r.L.

    HD9120 is an acoustic calibrator that, in accordance with the Circular Prot. RU 34143 of 02 December 2011, allows qualified technicians to perform calibrations of sound level meters for comparison with a reference sound level meter.

  • Daqarta v5.10 Data AcQuisition And Real-Time Analysis


    New Fcal option allows any Windows sound card to measure DC values like temperature or pressure using simple external circuits you can build yourself. Or, measure MHz frequencies with a simple prescaler. DAQARTA v5.10 turns your Windows sound card into a precision laboratory instrument, loaded with advanced features. Put your sound card to work!

  • Decoders

    LokSound - Electronic Solutions ULM GmbH & Co. KG

    With the LokSound family decoders we offer all model railroaders who want the utmost of authenticity on their layout, a real highlight. With LokSound , the excellent features of ESU-decoders are even more enhanced by the addition of sound functions. Its sounds simple, but “wow”: In the future, your locos not only run like the prototype, they sound exactly like it!

  • Very Low Frequency Control Element

    VLFC - Meyer Sound Laboratories Inc.

    Think extremely low. With a range of 13-30 Hz—the lowest reach of any Meyer Sound speaker—the VLFC extends below the threshold of human hearing to let your audience feel the sound like never before.

  • DC Measurements


    Standard Windows sound cards do not respond to DC or frequencies lower than a few Hz. (See Why Sound Cards Block DC Signals below for explanation.)There are two general approaches to get true DC response from a standard sound card: Modify the card, or add an external circuit to convert the DC into an AC signal which can be easily measured by an unmodified card.
