Indoor noise logging kit MATRON 4 Type 3668 is the fourth generation of kits for logging noise indoors from Bruel & Kjser, refined through years of experience. At its heart is Hand-held Analyzer Type 2250-L (2250 Light) with Class 1 measurement and sound recording capabilities, and a preconfigured measurement template that simplifies operation. MATRON 4 is typically used for domestic noise assessments in the United Kingdom according to the Environmental Protection Act 1990. The system is installed in an indoor environment, such as a home or an office, and left to continuously log noise data for up to 14 days. During this period, the noise levels are measured and stored, and the complainant makes sound recordings of disturbances by simply pressing a button. MATRON 4 includes a 1 year licence for one analyzer for Measurement Partner Suite BZ-5503, the post-processing platform (PC software) for Bruel & Kjser Hand-held Analyzers and the systems built on them, covering all the post processing functionality you will need when working with measurement data. Measurement Partner Suite also includes data storage in MP Cloud which can be useful when sharing data between offices.
