Zusammenfassung:	An acoustic transducer with an acoustic element that emits or receives front-side acoustic radiation from its front side, and emits or receives rear-side acoustic radiation from its rear side. A housing directs the front-side acoustic radiation and the rear-side acoustic radiation. A plurality of sound-conducting vents in the housing allow sound to enter the housing or allow sound to leave the housing. A distance between vents defines an effective length of an acoustic dipole. The housing and its vents are constructed and arranged such that the effective dipole length is frequency dependent.
