Lay Language Papers
Lay language papers are short versions of papers and talks presented at Annual Meetings of the Acoustical Society of America. Please keep in mind that some of the research described in the lay papers may not have yet been peer reviewed. See all papers here.
Frogs and toads are among the most vocal of all animals. Generally speaking, male frogs call to attract females and to defend their calling sites or territories from other would-be suitors.
Birdsong has long served as a model for vocal development and communication. Zebra finches are a particularly interesting model because they sing just one song their entire lives, and they sing this song with little variation from rendition to rendition. Male zebra finches sing to other males to defend their territories and to females for mating displays. Thus, perception of song is important for species survival.
There are many different sounds that people perceive as unpleasant or that may cause physiological reactions, like chills down the spine. These sounds include scraping a plate with a fork, squeaking Styrofoam or scratching fingernails on a chalkboard. Sometimes simply imagining these sounds or actions may cause the corresponding perception or physiological reaction […]. The aim of our study was to detect specific features of the sounds responsible for the perceived unpleasantness.
Studies show that musicians seldom use hearing protection despite being exposed to harmful sound levels on a daily basis. Noise-induced hearing loss does not distinguish between genres of music; as a consequence of overexposure to sound, famous artists such as Eric Clapton, Ozzy Osbourne, Pete Townshend, and Neil Young have reported suffering from hearing loss, tinnitus or both.
When the membrane is struck, many different modes or patterns of vibrations are excited, including the six important ones […]. Each of these modes of vibration has its own pattern of radiation.
