The Right tool for the job

It all starts with the right tool.

By far, the most important tool for the acoustician is the Sound Level Meter (SLM). As acousticians dedicated to understanding and managing sound environments, we rely heavily on the precision and accuracy of our instruments. So, how do we define the Sound Level Meter’s performance?
The IEC 61672, standard plays a role in classifying the performance of Sound Level Meters. The IEC 61672 standard sets the benchmarks and specifications that help us categorize these instruments into classes. These classes are essential in ensuring that the Sound Level Meters we use meet the required standards for accuracy and reliability.

Weather conditions

The elements of wind direction, wind speed, temperature, and humidity can significantly influence sound propagation. While these factors may seem inconspicuous in smaller enclosures, their effects crescendo in larger environments, like in scenarios involving traffic and industrial noise.

In confined spaces, the nuances of wind and weather might be overlooked, but as we expand our scope to larger distances, the sound waves we generate, whether from bustling traffic or industrial operations, encounter a sound travel path where wind, temperature, and humidity will shape their journey.

Wind direction and speed will aid or hinder the path sound takes.

Changes in temperature alter the speed of sound, impacting how far sound waves can travel. Meanwhile, humidity can affect the absorption of sound in the air.

In larger outdoor spaces, accounting for these variables is crucial in accurately predicting and managing noise levels.

Often times the weather conditions are the deciding factor for good measurements.

Aiming for pristine conditions may turn out to be a challenge!
