Peak sound pressure and sound exposure level from underwater explosions in shallow water.
Experimental measurements of the peak pressure and sound exposure level (SEL) from underwater explosions collected 7 km off the coast of Virginia Beach, Virginia are presented. The peak pressures are compared to results from previous studies and a semi-empirical equation that is a function of measurement range and charge weight, and are found to be in good agreement. An empirical equation for S...
متن کاملEmpirical estimation of peak pressure level from sound exposure level. Part II: Offshore impact pile driving noise.
Numerical models of underwater sound propagation predict the energy of impulsive signals and its decay with range with a better accuracy than the peak pressure. A semi-empirical formula is suggested to predict the peak pressure of man-made impulsive signals based on numerical predictions of their energy. The approach discussed by Galindo-Romero, Lippert, and Gavrilov [J. Acoust. Soc. Am. 138, i...
متن کاملSound pressure level generated by individual portable sound equipment.
INTRODUCTION The use of Personal Digital Audio Players can cause hearing injuries, as the sound is generated directly in the ear canal. It is believed that different types of headphones can cause different amplifications, since they cause changes in the volume and resonance of the ear canal according to their depth. OBJECTIVE This study aimed to determine the sound pressure to which young ind...
متن کاملEvaluation of Occupational Noise Exposure – Advantages and Disadvantages of Noise Dosimetry versus Sampling Using a Sound Level Meter
There are two methods for evaluating noise exposure in the workplace: dosimetry using a Personal Sound Exposure Meter (PSEM) and sampling using a sound level meter (SLM). This paper discusses the advantages and disadvantages of both methods in the context of the fundamental objectives of an occupational noise survey, i.e. identification of exposed workers, determination of exposure magnitude, a...
متن کاملRisk assessment of noise pollution by analyzing the level of sound loudness resulting from central traffic in Shiraz
Background: Today, the effects of environmental pollution on human life and human needs, which reduces the level of community health caused by traffic noise in large cities, are clearly visible by creating irritation and pathogenic conditions. The aim of this study was to assess the risk of noise pollution resulted from central traffic in Shiraz by analyzing its indicators and related componen...
