Exposure levels for parametric arrays in light of guideline ambiguities
Exposure levels for parametric arrays in light of guideline ambiguities
Recent revelations about ambiguities in guidelines for very-high frequency sound and ultrasound requiremany everyday devices to be revisited in terms of guideline compliance. One device that has a high ultrasound component but is designed for audio broadcast is a parametric array. Acoustic radiation for commercial parametric arrays was measured at a distance of 3.5 m in an anechoic chamber. The output of the device is compared against three international regulations and guidelines for ultrasound exposure. The authors found that the device was not compliant under the conditions tested in the laboratory

Abstract
Recent revelations about ambiguities in guidelines for very-high frequency sound and ultrasound requiremany everyday devices to be revisited in terms of guideline compliance. One device that has a high ultrasound component but is designed for audio broadcast is a parametric array. Acoustic radiation for commercial parametric arrays was measured at a distance of 3.5 m in an anechoic chamber. The output of the device is compared against three international regulations and guidelines for ultrasound exposure. The authors found that the device was not compliant under the conditions tested in the laboratory
