In the automotive industry, identification of noise sources is necessary to evaluate and reduce noise levels. As alternatives to intensity measurements, acoustic array techniques are currently being evaluated.

SOLUTION INVESTIGATION: The solutions to cable noise attributable to triboelectric effects include, among others: (1) in vibratory environments minimize cable “whip”, (2) in severe mechanical impact environments avoid

From computer disk drives that require extreme low noise testing, to loudspeakers, headphones and earbuds that require high amplitudes with minimal 1% Total Harmonic Distortion (THD) levels, PCB has an acoustic sensor tailored for your application.

Wilcoxon industrial accelerometers are designed to have the lowest possible noise at the frequencies actually being monitored. This is why specification sheets show both the ‘broadband’ (including the bandwidth) and ‘spectral’ noise specifications.

To begin you must understand the basic source-‐path-‐receiver paradigm for sound propagation. The problem must start with a device that generates sound waves (source).

Our portfolio features new and customizable accelerometers with smaller sizes and increasing levels of performance, force sensors with high resolution and fast response times, and new microphone models for low noise floor levels and challenging environmental conditions.

th a common acoustic phase center. The four channels of the vector sensor, when combined, produce a cardioid directivity pattern which provides approximately 4.8 dB improvement in the signal to noise ratio over a tradition.

In DFAN testing, a network of acoustic drivers surrounds the test article, creating an intense sound field that simulates the noise levels of a rocket launch.

premium high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range.

PCB Piezotronics, Inc. provides a variety of acoustic measurement products, including prepolarized and externally polarized condenser, array, probe, low-profile surface, and special purpose microphones.

charge amplifiers are designed with more effective low-noise circuits and may incorporate simplified LCD displays and digital controls. Some "dual-mode" models operate with both PE and ICP ® accelerometers. The main advantage of the laboratory charge system is flexibility of adjusting and controlling the electrostatic

Whether you're testing computer components with our low-noise microphone system (model 378A04) or assessing loudspeakers, headphones, and earbuds using our phantom powered system (model 376A33), rest assured, we have the perfect acoustic sensor for your application.
