Microphones & Preamplifiers
The identification of noise sources is necessary to evaluate and reduce noise levels. “Noise” denotes unwanted sound, and hence, the need to negate these sounds and vibrations. Vibrations above and below a specific range may not be detectable to the human ear, but may still require treatments for improved product performance and longevity. The frequency of the noise is paramount, as it dictates which method of treatment or what material will work best.
As alternatives to intensity measurements, acoustic array techniques are currently being evaluated. Often, when a method is found to provide useful information for one test object in one environment, an attempt is made to apply it in situations where it is not necessarily advantageous. Unfortunately, there does not appear to be a single method of source identification that is easy, quick and accurate for all applications. This is why PCB® offers a variety of acoustic measurement products, including condenser, modern prepolarized, traditional externally polarized, array, probe, low-profile surface, and special purpose microphones. PCB® Microphone products are complemented by an assortment of preamplifiers, signal conditioners, A-weighting filters, handheld calibrators, and accessories.
From ready-to-ship stock products, to custom-made specials, PCB® proudly stands behind all products with services you value most, including our 24-hour technical support, global distribution network, and the industry's only commitment to Total Customer Satisfaction.
