Acoustical airspeed indicators
1950Some of the problems associated with the applications of acoustical devices for the determination of airstream characteristics are considered in this study. The velocity and pressure fields for both point sound sources and finite sound sources in both subsonic and supersonic flow are discussed, with a view toward using sound waves for the determination

Acoustic environment as an indicator of social and physical context
Personal and Ubiquitous Computing, 2005Acoustic environments provide many valuable cues for context-aware computing applications. From the acoustic environment we can infer the types of activity, communication modes and other actors involved in the activity. Environmental or background noise can be classified with a high degree of accuracy using recordings from microphones commonly found in

Acoustic consequences and perceptual indicators of stress
The Journal of the Acoustical Society of America, 1978All telephone conversations of Consolidated Edison's system operator beginning an hour before the 1977 New York blackout were studied for indications of emotional stress. The system operator had primary responsibility for monitoring and switching power loads in the New York area.

Relative Indications for Radiosurgery and Microsurgery for Acoustic Schwannoma
2003The physical and biological principles underlying the use of radiosurgery for the treatment of vestibular schwannomas of up to 2.5 cm in diameter are reviewed together with the historical controversies that have surrounded its introduction. The results in terms of mortality, quality of life, preservation of facial movement and hearing, incidence of ...

Indications for Diagnostic Labyrinthotomy: In Acoustic Neurinoma Suspects
Archives of Otolaryngology - Head and Neck Surgery, 1971Diagnostic labyrinthotomy is indicated in acoustic neurinoma suspects: (1) when there is a progressive unilateral sensorineural loss and the laminograms of the internal auditory canals show no abnormalities; (2) when the posterior fossa contrast study is equivocal or unsatisfactory; (3) when there is a question of whether the filling defect represents ...

Acoustical properties of speech as indicators of depression and suicidal risk
IEEE Transactions on Biomedical Engineering, 2000Acoustic properties of speech have previously been identified as possible cues to depression, and there is evidence that certain vocal parameters may be used further to objectively discriminate between depressed and suicidal speech. Studies were performed to analyze and compare the speech acoustics of separate male and female samples comprised of ...

Acoustic Indicators for Mapping Infestation Probabilities of Soil Invertebrates
Journal of Economic Entomology, 2007Acoustic and traditional excavation methods were used in consecutive summers to conduct two geospatial surveys of distributions of white grubs and other soil invertebrates in two forage fields. Indicator variables were constructed from listener- and computer-based assessments of sounds detected at each recording site and then applied in geostatistical ...
