HBK microphone cartridges are suited for a wide range of measurement applications. Four types of microphones define the sound field and adaptability for specific environments, industries, and measurement conditions, and are referred to as free-field, pressure-field, diffuse-field, and special microphones. HBK microphone cartridges are supplied in 1 inch, 1/2 inch, 1/4 inch or 1/8 inch diameter size, and require a microphone preamplifier.

The high‐output current capability of our preamplifiers is able to drive extremely long cables without signal degradation - even when measuring high sound pressure levels present at high frequencies. The HBK CCLD and classical preamplifier designs fit our range of 1/2" and 1/4" microphone cartridges.

A microphone set combines a HBK microphone cartridge paired with the ideal microphone preamp (preamplifier). Each microphone set carries a unique ID and a memory chip, sealed to form a single unit – also called a TEDS microphone. TEDS technology enables easy setup and reliable measurement results.

HBK hydrophones are individually calibrated, waterborne‐sound transducers. The instruments deliver a flat frequency response and are omnidirectional over a wide frequency range. All hydrophones are built with a shielded-element construction; completely waterproof, corrosion-resistant, and are able to withstand high levels of salinity. The instruments provide unrivaled depth, range, and precision when measuring sound in the lab and in ocean research.

Sound sources such as impact generators, loudspeakers and power amplifiers designed for room and building acoustics measurements. Each sound source ensures full compliance with both national and international standards.

The high reliability of electronic measuring instruments such as sound level meters enables you to make accurate measurements after a simple check with one of our acoustic calibrators. In many cases this check is also carried out after each measurement to validate the results. To make sure an instrument is working correctly, more comprehensive checks are required periodically making the portable acoustic calibrators an excellent choice for making highly accurate, in-field calibration of your measuring instrument.

Special microphones designed for specific measurement applications. HBK provides special microphone types ranging from outdoor microphones, surface microphones, array microphones, and probe microphones. Each microphone provided with ranging adaptability for specific environments and measurement conditions.

Laboratory standard microphones are specifically built for extreme stability. The standard microphone is perfectly suited as laboratory reference microphone.

Acoustic material testing designed for measuring the acoustical properties of sound and noise control materials. The material testing kits are supplied with testing tubes, microphones, and sound sources, providing you with a complete system, to test the acoustic performance of road surface absorption, insulation, and general noise control materials.

Microphone accessories are vital pieces of equipment for achieving accurate results. Particularly in outdoor measurements where wind, rain, and turbulence can influence measurement results, the right equipment can help mitigate the environment. HBK high-quality cables, tripods, windscreens, holders, and measurement kits, are designed to deliver accurate results - in any environment.
