We are all familiar with the relentless advance of technology. To a certain extent, sound level measurement has taken advantage of this in a number of areas. The computing power and communication possibilities in a handheld device far surpasses that which was on our desktops 20 years ago and this has tremendously increased the flexibility of measurement applications that can be met in the field. Logging sound level meters previously capable of storing only days of processed data (e.g. broadband and 1/3-octave values and statistics) effectively now offer unlimited storage up to and including full recordings Technology has helped right through to post processing where data can now be easily post processed into different metrics and reports to ensure the data communicates what was really happening at the measurement location. Unfortunately there is a significant time lag. Technology developments often take years to make it through to the sound level meter and the market. This creates a mismatch between market expectations and what is available. However this time lag is shrinking. This paper describes how the latest technology advances in wireless communications, cloud data management and smart devices are capable of not just transforming the sound level meter itself, but the way in which it is used. The next adoption cycle will deliver greater measurement accuracy and consistency as well as significantly improving efficiency enabling users to get more done with their sound level meter.
