Abstract: In some examples, an acoustic input device includes a housing comprising a plurality of acoustic ports, and a plurality of single-port acoustic transducers within the housing to receive respective acoustic waves from an environment outside the acoustic input device through corresponding acoustic ports of the plurality of acoustic ports, where a first acoustic port of the plurality of acoustic ports is located on a first surface of the housing, and a second acoustic port of the plurality of acoustic ports is located on a second surface of the housing that is opposite the first surface. The acoustic input device further includes a controller within the housing to receive outputs of the plurality of acoustic transducers.
