B&K 2245-N sound-level meter is the perfect solution for monitoring environmental noise

The 2245-N sound-level meter by Brüel & Kjær

Durham Instruments sells a variety of great test and measurement solutions by Brüel & Kjær. This includes the B&K 2245-N sound-level meter (SLM), a robust, waterproof, and dust-resistant device that can be used in areas with grit, grime, or poor weather. It helps workers to comply with provincial guidelines for noise exposure. Simple to connect via Wi-Fi to a Smartphone, this SLM device allows operation from any convenient remote location away from the sound field with an app control interface.

With measurement-status light ring

A versatile unit that meets the IP55 standard, this meter is appropriate for applications in many sectors. Applications and scenarios that benefit from the 2245-N include checking sound-pressure levels (to ensure fire alarms meet regulations, for instance), broadband measurement that requires devices that meet specific standards, and simple product testing to confirm other safety compliance. The Durham Instruments team recommends this SLM for use in the general manufacturing, aerospace, automation, food-processing, forestry, medical, military, mining, packaging, power-generation, alternative-energy, and transportation industries and for research and development.

Each province in Canada has a distinct set of criteria for occupational noise levels to prevent noise-induced hearing loss in workers. For example, Ontario has a maximum-exposure limit of 85 dbA, while British Columbia has a daily limit of 85 dbA and a peak limit of 140 dbC. These limits can vary with the amount of time exposed to extreme noise in Saskatchewan and Alberta. The B&K 2245-N keeps facilities aware of sound levels to stay below these limits.

This SLM comes with the Noise Partner app pre-installed. Users need little training to use this app, which is designed for simple broadband measurement, general-purpose sound-pressure-level measurement, or basic occupational, product, or noise measurement in the environment. Among the instrument’s other key features:

• built-in Li-Ion battery
• colour LDC with bright, clean layout
• integrated GPS for time and location
• integrated Wi-Fi Bluetooth Low Energy
• measurement-status light ring
• single measurement range from 15.2 to 140 decibels, from typical noise floor to maximum level, A-weighted
• 16 gigabytes of built-in storage for measurement and annotation
