Available in PDF, EPUB and Kindle. Book excerpt: Acoustic measurements were made of the sound pressure level-time functions which were produced at six locations on Cape Canaveral Missile Test Annex and at four locations in the surrounding communities during the Saturn SA- 1 launch on 27 October 1961. The frequency range of measured data was from the 4.7 to 9.4 cps octave band to the 4800 to 9600 cps octave band. Distances from the launch site to the noise measuring sites ranged from 3700 to 100,000 feet. Vibration data were taken at three locations at the Tel-2 telemetry site. The frequency range of measured data was from the 4.5 to 9 cps octave band to the 1125 to 2250 cps octave band. The distance from the launch site was 5200 feet. Only the basic sound pressure level-time environments and vibration level-time environments as a function of octave bands of frequency are presented in this report.

This book was released on 1967 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound attenuation and transmission loss characteristics of three different earmuffs models were determined from (1) physical measurements of discrete frequency signals in the range from 1 to 500 Hz inside and outside earmuffs being worn by subjects and (2) psychoacoustical or subjective measurements employing the United States of America Institute of Standards 'Real Ear Attenuation at Threshold Method.' Evaluation of the data showed good correlation between the two measurement methods. Greater attenuation was obtained with the subjective method. It was interpreted to be due primarily to the masking effects at threshold of hearing of physiological noise present under the earcups. Findings show that typical present-day earmuffs provide approximately 10 dB of attentuation in the frequency range from 20 to 100 Hz and very little sound protection below 20 Hz. It is recommended that insert earplugs be used for sound protection in intense low audio frequency and infrasonic sound fields. Good earmuffs in combination with insert earplugs should provide more protection than earplugs alone. (Author).
