ASTM E596 is a standard test method that measures the noise reduction of sound-isolating enclosures. It provides details about the noise isolation class by measuring the noise reduction. The enclosure is placed in a reverberation room to ensure safe and proper testing. The final results are displayed in accordance with international standards.
ASTM E596 Standard Test Method for Laboratory Measurement of Noise Reduction of Sound-Isolating Enclosures
What is ASTM E596?
What is the Scope of ASTM E596?
The ASTM E596 test method covers measuring the noise reduction of sound-isolating enclosures in a reverberation room. This provides details on sound-isolating enclosures and helps rank them by noise-isolation class. The results from this method support quality control, research, and performance evaluation of various sound-isolating enclosures.
ASTM E596 Sample Preparation Guide
Specimen size should meet the requirements. In this case, a one-third octave filter set is used, with frequencies ranging from 125 to 4000 Hz. The signal level should be at least 10 dB above the background noise level.
ASTM E596 Testing Procedure and Requirements
The sound-isolating enclosure is prepared and placed in a reverberation room. The noise levels are adjusted and measured with respect to one-third octave bands. The one-third octave band sound pressure is measured on the onset of bands of random noise. The noise reduction data is taken and stands for the difference between the space-averaged sound pressure level in the reverberation room and that in the enclosure. The noise isolation data then helps in the determination of the noise isolation class.
ASTM E596 Analysis Results and Interpretation
The signal level is corrected by applying the formula if the background noise level is between 5 and 10dB, where ‘L’ stands for the signal level, and ‘NR’ stands for the noise reduction.
