Analysis of acoustic communication by ants

Journal of the Acoustical Society of America, 2000
An analysis is presented of acoustic communication by ants, based on near-field theory and on data obtained from the black imported fire ant Solenopsis richteri and other sources. Generally ant stridulatory sounds are barely audible, but they occur continuously in ant colonies.

Acoustic Communication in Noise

2005
Publisher Summary Environmental noise can affect acoustic communication through limiting the broadcast area, or active space, of a signal by decreasing signal-to-noise ratios at the position of the receiver. At the same time, noise is ubiquitous in all habitats and is, therefore, likely to disturb animals, as well as humans, under many circumstances.

Communication acoustics

The Journal of the Acoustical Society of America, 2004
Those aspects of acoustics which concern the relations of acoustics to the information and communication technologies are now frequently called ‘‘communication acoustics.’’ After a short review of the history of this field, relevant results from recent research at the Institute of Communication Acoustics at the Ruhr-University of Bochum, Germany, will ...

The importance of acoustic reflex for communication

American Journal of Otolaryngology, 2011
The purpose of the study was to compare the speech recognition capacity between listeners with and without acoustic reflex using different types of noises and intensities.We studied 18 women allocated to 2 groups: acoustic reflex present (20 ears) and absent (16 ears).

The acoustic climate of plant communities

Oecologia, 1976
During summer season and winter season of 1971 and 1972, the acoustic properties, defined as the acoustic climate, of 8 semi-natural plant communities in the Netherlands were investigated. It appeared that each plant community has its own acoustic climate as a consequence of the specific species composition and the specific acoustic properties of the ...

Habitat acoustics and primate communication

American Journal of Primatology, 1986
AbstractThe acoustic characteristics of three tropical habitats were investigated to determine how they might constrain the structure of primate signals. Ambient noise was measured, along with signal attenuation and aspects of signal degradation (reverberation, amplitude fluctuations, and pulse train modulation depth). These measures allowed estimation

Semio-acoustics: a domain of communication acoustics

The Journal of the Acoustical Society of America, 2008
For user-oriented design of modern information and communication systems we investiate the perception of acoustic signals as sign carriers: How do listeners process acoustic/auditory events when they treat them as information carriers and which meaning do they associate with them?

OFDMA for underwater acoustic communications

2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011
We investigate the possibility of using orthogonal frequency division multiple access (OFDMA) for design of efficient underwater acoustic (UWA) networks. The major challenge for the OFDMA-based UWA communication systems is the Doppler-induced frequency scaling, which may cause severe intercarrier interference (ICI), and depending on the particular user
