ISO9614-2
The ISO 9614-2 standard describes how to use sound pressure in an acoustic environment to determine the sound power level of noise sources. The measurement of sound power levels in circumstances where the sound source functions in a controlled environment, like a laboratory or suitable testing facility, is the specific focus of this section of the ISO 9614 series.
Use of ISO9614-2:
Engineers and acousticians use acoustic performance evaluation to quantify the sound power that machinery, equipment, and other noise sources emit in a controlled setting.
Regulatory Compliance: Assists producers in making sure their goods abide by applicable noise laws and sound emission standards.
Product Development and Certification: Offers manufacturers a standardized process for evaluating and approving the acoustic performance of their goods.
Method of ISO9614-2:
Test Configuration:
To ensure precise sound pressure readings, the measurement is carried out in a setting that reduces outside noise and reflections.
To guarantee consistent and dependable results, the noise source should be positioned in accordance with the guidelines.
Method of Measurement:
Sound Measurement: A variety of microphones are used to record the sound pressure levels at different angles and distances from the noise source.
Data collection: To capture the total sound emissions during operation, measurements are made to record sound levels over a predetermined time period.
Monitoring of Background Noise: To take into consideration any interference in the measurements, background noise levels are tracked.
Analyzing Data:
The measured sound pressure levels, which are usually given in decibels (dB), are used to compute the sound power level.
Frequency analysis may be included in the results to demonstrate how sound power changes with frequency.
ISO 9614-2 is essential for precisely determining sound power levels in controlled settings, supporting adherence to noise regulations, and enhancing the acoustic performance of machinery and equipment in a range of applications.
