Clearer, Quieter Cell Phones Under Development

The Acoustical Society of America's 158th meeting next week in San Antonio brings together many of the world's acoustics experts to hear more than 650 talks on such research.

The progress of research to make cell phones less bothersome in public spaces and to improve their sound quality will be presented during the Acoustical Society of America's 158th meeting next week in San Antonio. This ASA event brings together many of the world's acoustics experts to hear more than 650 talks and review posters dealing with music, noise suppression, medicine, psychology, and more.

At 4 p.m. Oct. 26, Yu-Hao Hsieh of National Cheng Kung University in Taiwan will discuss work being done there to reduce noise and distortion in voices on 3G phones through time reversal signal processing, which boosts the signal-to-noise ratio by comparing the waves sent out to those reflected back. An abstract of his presentation is available here.

Cheol Hong Kim of Chonnam National University in Korea is working on cell phones that automatically adjust the volume of their ringtones based on the loudness of the surrounding environment. He will present preliminary results from a study that looks at the relationship between the environment (temperature, vibration, ambient noise, and humidity) and ringtone loudness at 11:50 a.m. Oct. 30. Visit this page for an abstract of the presentation.

The 2009 Munk Award will be presented Oct. 28 to James F. Lynch of the Woods Hole Oceanographic Institution. The award and medal are granted jointly by The Oceanography Society, the Office of Naval Research, and the Office of the Oceanographer of the Navy; this will be the first time the award has been presented at an ASA meeting. Lynch will present the Munk Award Lecture, "Acoustical oceanography and shallow water acoustics," at 3:45 p.m. Oct. 27.
