What is an acoustic metal foam device?

Acoustic metal foam devices are generally microphones designed for professional use.  Using aluminum foam provides electrical and wind shielding, to minimize sound coloration.

Who uses acoustic metal foam devices?

Foam microphones are considered high end and used by professional recording artists in the studio.  They may also be used to capture sounds in nature by biologists and other researchers.

How does Duocel® make a great microphone?

Duocel foam makes an excellent microphone because the open cell structure and high uniformity accurately capture high quality audio signals.  Acoustic metal foam not only reduces wind noise and other interference, the metal isolates voices and reduces background noise by reflecting outside sounds within the arc of the inner foam microphone.
