Noise Assessment according to BS 4142:2014 with the XL2

The XL2 Sound Level Meter is built for precisely measuring and recording industrial and commercial sound. The Data Explorer PC-software evaluates the recorded data in detail and calculates the Rating Level Lr. A character correction for tonality and impulsivity can be automatically added using the objective method detailed in BS 4142:2014. This provides an expert tool for rating and assessing sound of an industrial and/or commercial nature.

The assessment, according to the British standard BS 4142, is based on measuring the average sound pressure level LAeq over a representative period of time. Humans generally find that sounds with tonal or impulsive components are more disturbing than those without. The increased annoyance is considered with a penalty. The sum of the measured sound level and the individual penalties produces the rating level Lr for comparison with the applicable legal directive.

Austrian Convention Center puts their trust in the XL2

The stunning Montforthaus Culture and Convention Center in Feldkirch, Austria, was officially opened in January 2015. Symphony concerts, fairs, social events, conferences, club events, school balls, lectures and pop concerts are a regular feature in this conference and congress facility which can accommodate up to 3,000 participants. The audio quality and intelligibility of speech presentations in these many and varied acoustic environments is assured by the XL2 Acoustic Analyzer.

The Montforthaus technical team considers the XL2 Acoustic Analyzer an essential part of their kit. With often incredibly quick turnaround times between events, the audio quality tasks need to be handled efficiently. These include optimizing the sound quality on the stage and in the auditorium as well as monitoring sound levels during events. Further, the functionality and intelligibility of evacuation announcement system needs to be periodically verified.
