1. Acoustic Transducers:

Microphones – 1-inch, 1/2-inch, 1/4-inch and 1/8-inch microphones for measurement of Sound Pressure Levels in different fields.

• Free Field Microphones – For measurements away from reflecting surfaces like outdoor or acoustically well-damped indoor environment.
• Pressure field microphones – For measurements in small closed couplers or close to hard reflective surfaces.
• Diffused field microphones -  For measurement where signals arrive simultaneously from all directions.
• Muiltfield Microphones- Unique Microphone for measurements in any field or when field is unknown.
• Surface Microphones- Flat Microphone for flush mounting on surfaces.
