On-Site Acoustic Testing provides field measurements supporting machinery and equipment noise-emission declarations, including projects using ISO 4871.
ISO 4871 addresses the declaration and verification of machinery and equipment noise-emission values. The appropriate measurement method depends on the machine, operating condition, installation and applicable product or industry standard.
Sound Power and Emission Measurements
Noise declarations may rely on sound-power or emission sound-pressure data produced under an applicable measurement standard. OSAT can develop a field measurement approach around the required operating condition and documentation. Where appropriate, testing can incorporate sound intensity and sound-power measurements and frequency-spectrum analysis.
Manufacturer and In-Situ Testing
Testing can support manufacturers, equipment suppliers and end users where machinery must be characterized at a factory, installation site or other suitable measurement location. The applicable declaration and verification requirements should be established from the governing product standard and project requirements before testing.
Discuss a Machinery Noise Project
Provide the equipment type, operating conditions, applicable standard or specification and intended use of the results so an appropriate test plan can be developed.
