The crystal in a crystal earpiece is a piezoelectric sound transducer. Back in the 1960s, these were fairly common in cheap transistor radios and hearing aids. Their sound fidelity isn’t very ...

Active sonar and acoustic communication systems rely on electroacoustic transducers which "project" sound that is subsequently detected by hydrophones through a direct path or reflection from a target ...

Usually sound isn’t something you want in your ordinary 3D printers unless you are playing music on them. We don’t know if the usual levitation transducer would work in this context ...

In this study, the research team developed an ultra-compact (1 mm²) transparent ultrasonic transducer capable of delivering high-resolution ultrasound and photoacoustic imaging simultaneously.

The transducer was constructed using transparent materials, including indium tin oxide electrodes and urethane sound-absorbing layers, which preserve the transducer's structure while allowing the ...

Sound Level Meter Unit for measuring sound pressure level (SPL) and different weightings such as A-weighted SPL, C-weighted SPL, sound exposure level, etc. Noise Dosimeter Specific measurement ...
