Guidelines for Noise Pollution Prevention - Noise Exposure Meter NB-14
The "Guidelines for the Prevention of Noise-Induced Disorders," aimed at preventing noise-related disorders in workers engaged in noisy operations, was revised on April 20, 2023, by the Ministry of Health, Labour and Welfare. NB-14 is a noise exposure meter that meets the accuracy requirements specified in the revised guidelines (Appendix 3) for "personal exposure measurement." *1 Meets the accuracy specified in JIS C1509-1 or IEC 61252. Applicable Standards IEC 61252:1993+AMD1:2000+AMD2:2017, IEC 61672-1:2013 class 2, JIS C 1509-1:2017 class 2 VCCI Class B CE Marking EMC Directive 2014/30/EU, RoHS Directive 2011/65/EU UKCA Marking China RoHS Directive Accessories Dedicated USB cable Dedicated windscreen Holder for crocodile clip

Applications/Examples of results
- For the prevention of noise-induced hearing loss in individuals working in noisy environments. - As reference data for the selection of hearing protection equipment. - When the source of noise or the workers exposed to noise move, there may be cases where accurate noise measurement cannot be conducted. In such situations, this serves as an alternative measurement for B measurements of the working environment. (*In this revision of the guidelines, personal exposure measurements have been newly added for this purpose.) - The AS-05View software, which allows for easy downloading of data and report creation, can be downloaded for free when the main unit is connected to a USB cable (charging cartridge). - Reports compliant with the guidelines can also be easily created by connecting the main unit to a USB and using the software (AS-05View). Additionally, measurement data can be viewed on a smartphone app.
