Qind2 Low Frequency Miniature Source

The Low Frequency Miniature Source has been developed to perform highly repeatable, low frequency acoustic excitation in a minimum of space. The two domes are placed centrally to enable a monopole noise emission from the center. The drive system allows a large stroke for maximum air displacement in a minimum amount of space. An internal sensor provides a real-time voltage which is proportional to the generated volume displacement. This enables engineers to measure calibrated acoustic and vibro-acoustic FRFs
