Anechoic Chambers
Eckel Noise Control Technologies
Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements or SuperSoft panels, depending on performance level required and cut-off desired.

Acoustic Analysis
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.

Noise Meters
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
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.

Stationary Sonaphone For Online Monitoring Of Processes And Machines
SONAPHONE® S-SB10.xx
With the Stationary SONAPHONE S-SB10.xx and its associated probes machine and plant processes can be monitored permanently, insofar as a detectable ultrasonic level is generated. A fixed installation at an inspection point enables trend monitoring for longer periods. Based on changes of the ultrasonic sound level the assessment of plant condition is possible. Different probe versions support airborne sound and structure-borne sound applications.

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.

Ultrasonic thickness gauge
The frequency range of sound that can be heard by the human ear is about 20Hz to 20KHz, and sound waves with higher frequencies are called ultrasonic waves. In general ultrasonic flaw detection equipment, 5MHz is often used in the range of 1MHz to 20MHz as standard.
