Architectural shape and early acoustic efficiency in concert halls (L).
Supplying sufficient early reflections to audience members is an important prerequisite to good acoustic quality in performing arts spaces. However, the relationship between the geometry of a room and its acoustic efficiency in terms of early energy has rarely been investigated using basic geometrical principles. The present study demonstrates the possibility of predicting the average value of ...
متن کاملExposure to loud noise and risk of acoustic neuroma.
Exposure to occupational loud noise has been previously identified as a possible risk factor for acoustic neuroma in only one relatively small (n = 86 cases) case-control study of men. The goal of the present study was to further examine the role of loud noise in acoustic neuroma etiology. In their population-based case-control study of both sexes conducted from 1999 to 2002 in Sweden, the auth...
متن کاملOccupational noise exposure and risk of acoustic neuroma.
A small number of prior epidemiologic studies of occupational noise exposure based on self-report have suggested an association with acoustic neuroma. The goal of the present study was to further examine the association between noise exposure and acoustic neuroma by using an objective measure of exposure in the form of a job exposure matrix. A total of 793 acoustic neuroma cases aged 21-84 year...
متن کاملOriginal Contribution Loud Noise Exposure and Acoustic Neuroma
The results from studies of loud noise exposure and acoustic neuroma are conflicting. A population-based casecontrol study of 451 acoustic neuroma patients and 710 age-, sex-, and region-matched controls was conducted in Sweden between 2002 and 2007. Occupational exposure was based on historical measurements of occupational noise (321 job titles summarized by a job exposure matrix) and compared...
متن کاملRisks of acoustic noise in the MR environment
Introduction MRI acoustic noise represents a possible hazard to patients and volunteers undergoing scanning and to workers present in the scanner room during imaging. Vibrations in the gradient coils are generated by Lorentz forces, induced by the currents flowing through the gradient coils within the static magnetic field. The vibrations are transmitted to other parts of the scanner and finall...
