Acoustic Testing

Noise Source Identification (NSI) and Mapping
NSI helps you determine the design changes of your product in order to reduce the noise emitted.

Sound Quality
In addition to offering powerful tools for objective and subjective analysis of product sound quality, this software also provides complete facilities for sound quality (SQ)evaluation and optimisation. Objective results can be quickly correlated with subjective findings using the built-in tools so you can develop the SQ metric that best represents your customers' preferences.

Sound Power
PULSE Value Pack for Sound Power Determination software offers solutions for measuring sound power using both intensity and sound pressure methods in accordance with international standards. The software guides the user through the measurement procedure, performing the calculations and validation.

	NVH Vehicle Simulator NVH Simulator provides a realistic way of evaluating NVH data by adding two critical factors to the traditional NVH evaluation process, namely interactivity and context. Interactivity allows the assessor to be in control of the sound (and vibration) data representing a particular vehicle through the use of throttle pedal, brake pedal, and gear selector.
	Pass-by Noise Testing This complete PULSE-based exterior vehicle noise measurement platform covers outdoor pass-by according to all common standards, or even user-defined standards. In-car (RPM, throttle position, oil temperature, etc.) and environmental parameters are measured. An indoor pass-by option is also available for detailed exterior noise tuning and control.
	Checking NVH variability of production vehicles using 2250 Analyzer Brüel & Kjær’s Hand-held Analyzer Type 2250 helps you improve the reliability and quality of vehicles and components. Simple to use and cost-effective, Type 2250 provides accurate and instant results with the minimum of effort and investment.

Acoustic Material Testing
PULSE Material Testing is a complete system for making acoustic impedance, absorption or transmission loss measurements on material samples in the 50 Hz to 6.4 kHz frequency range. The system consists of PULSE Material Testing Program, our impedance or transmission loss tubes, and other items such as a precision power amplifier, cabling, and dedicated microphones.

Surface Pressure Fluctuation
The aerodynamic design of a vehicle is probably the most important parameter seen from both an aesthetic and fuel consumption viewpoint. Therefore, measurement of surface pressure fluctuations directly in the airflow in a wind tunnel provides the aerodynamics engineer with valuable information.

	SoNoScout Binaural Recording and Analysis System SoNoScout Type 3653-B is an automotive tool for two-channel sound data acquisition and analysis. SoNoScout is ideal for obtaining and processing binaural data for use with NVH Simulator models.

Sound Quality

The sound quality of the noise from a product is of ever-increasing importance when assessing the total quality of the product. For products ranging from cars to hand tools, not only the level but also the quality of the noise it makes is part of what attracts or repels the customer; the right sound can lead to increased sales.

Many factors come into play in the sound quality evalua...

Sound Power

Noise emission values are increasingly becoming the subject of regulations for a safer and healthier working place and for the protection of the environment.

Moreover, awareness among consumers regarding noise issues has substantially increased and voluntary awards for companies who meet acoustical criteria are becoming a product differentiator.

In cases where the noise emiss...
