Building Acoustics

Measurements to evaluate and improve Building Acoustics are typically made to analyze and design noise control from room to room, or from outside to inside.   Noise sources such as music systems, televisions, appliances, traffic, aircraft, and manufacturing are all around us.  The field of Building Acoustics evaluates and designs the materials and methods to insulate and isolate us all from these sound sources when we are at work, rest, or enjoying leisure time.  The resulting data is useful for evaluating compliance with building codes and for proposing countermeasures for areas of concern.  These measurements often involve creating and measuring an artificial sound source, and then measuring the resulting noise in receiver locations.

Modern Prepolarized Precision Condenser Microphones & Preamplifiers

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Modern prepolarized microphones are designed with newer technology than traditional externally polarized microphones. Prepolarized microphones have many advantages over the externally polarized models. They use ICP® power circuitry invented for sensors by PCB®. By applying a polymer coating to the top of the backplate and embedding a charge on it, expensive 200V power supplies can be eliminated and 2-20 mA constant current supplies or signal conditioners can be used as the power source.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Three-component dynamic force sensors are offered in both ICP® and charge output configurations for dynamic and quasi-static force measurement applications. Each utilizes an array of precision aligned, quartz sensing crystals. Measurements along the z-axis are proportional to applied compression, tension and impact forces. Measurements along the x and y axes are proportional to shear forces that are imposed upon preloaded crystals by the test fixture.

Low Noise Prepolarized Microphone

378A04

PCB Piezotronics, Inc.

378A04 - PCB Piezotronics, Inc.

The 378A04 is a matched system that is comprised of a 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. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

High Temperature ICP® Accelerometers

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

PCB® offers specially designed and tested ICP® accelerometers for conducting vibration and shock measurements under demanding environmental conditions of up to 356 °F (180 °C). These sensors combine proven quartz and ceramic shear sensing technology with specialized, built-in microelectronic signal conditioning circuitry to achieve dependable operation in extreme temperatures and through repetitive temperature cycling. Laser-welded, hermetically sealed, lightweight titanium or stainless steel housings offer further protection from the environment. Prior to shipment, each sensor undergoes a battery of tests to ensure survivability for its intended use. Such tests include temperature soak at elevated temperatures, temperature cycling, and exposure to highly accelerated screening procedures with hydraulically actuated shakers.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Motion of a rigid body can be characterized within six degrees of freedom. Providing mechanical excitation to simulate this motion as may be encountered in the real world can entail a variety of test machines. There are various pound/force vibration shakers for structural testing. Regardless of the apparatus, the goal is always to ensure that the product under test can adequately perform, and reliably survive, in the environment in which it will be deployed, or to which it will be exposed during transport. PCB® accelerometers provide the measurement signals needed to control the vibratory input and to analyze the product’s reaction to such testing.

ICP® Shock Accelerometers

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Piezoelectric ICP® accelerometers afford a very high signal output (+/- 5 volts full scale) and the ease of two-wire electrical connectivity. Their inherent ruggedness enables them to be severely over ranged without damage. The addition of internal mechanical isolation minimizes the high frequency stress that would otherwise be encountered by their ceramic sensing elements. This mechanical isolation, coupled with an internal 2-pole electrical filter, built into the ICP® circuitry, tailors the overall accelerometer response to assure data quality to frequencies as high as 10 kHz. Depending on the specific model, accelerations in excess of 50 kg can be successfully measured. These modern designs, with their internal elastomeric isolation materials are verified through calibration to remain dynamically linear and are enabling piezoelectric accelerometers to operate in increasingly severe acceleration environments.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Piezoresistive shock accelerometers, manufactured by MEMS technology, have low power consumption while still providing +/- 200 mV full scale output. They afford a wider operating temperature range when compared to mechanically isolated ICP® accelerometers. Their frequency response ranges from DC (0 Hz) to 20 kHz. To lessen the severity of response when their resonant frequency is excited, they incorporate squeeze film damping, achieving values of 0.02 to 0.06 of critical.
