c ○ IEEE Aerial Communications using Piano, Clarinet, and Bells

Abstract — This work explores novel mechanisms for aerial acoustic machine-machine communications. It builds on previous work by some of the authors [1], as well as others [2]. In this paper we describe aerial acoustic communication systems that sound like musical instruments. The sound primitives come from simple models for the sound of the piano, the clarinet, and the bells. The messages are coded by combining these primitives according to musical harmony. Our experiments show that these communication systems are well suited for applications requiring very low bit rates. Examples of the acoustic signals produced are made available from the WWW. I
