These articles describe sound measurement performed with a
handheld sound level meter and give useful advice for assessing
noise in the environment and sound in a range of applications.

Low-frequency noise? We’ve got it cornered

Annoyance from low-frequency noise is increasingly recognized as a problem in multi-family residential buildings. Unfortunately, low-frequency sound insulation is difficult to determine accurately, particularly in smaller rooms such as bedrooms – precisely the kinds of rooms where low-frequency noise is most likely to cause annoyance.

What is a Sound Level Meter?

A Sound Level Meter (SLM) is an instrument (commonly hand-held) that is designed to measure sound levels in a standardized way. It responds to sound in approximately the same way as the human ear and gives objective, reproducible measurements of sound pressure levels.

Sound Intensity and Sound Power Relationship

音響パワーと音圧

音響パワーとは、単位時間あたりに音源が放射した空気中の音響エネルギーの総量です。一方音圧は、音源が放射した音のエネルギーが、その場の音響環境の影響を受けて測定された物理量です。音響パワーは原因、音圧は環境の影響を受けた結果といえます。

Time to invest in a new sound level meter?

Having the right tool for the job makes you efficient – and that is good business. In this article, we look at some of the things you should consider before deciding on whether to replace your old sound level meter.

Leq and SEL - When to choose what?

Leq and SEL are energy parameters which provide a very useful means of describing fluctuating sounds. In this application note we will look at what Leq and SEL are; What is the difference between between them, and when do we use them?

18 Tips For Successful Sound Measurements

Conducting sound measurements requires a sound level meter of course, but the sound level meter itself is only one of the many things you need to remember when on a measurement job. In this checklist, we have collected 18 tips to help you get successful measurement results.

Get Started With Your Sound Level Meter

Detailed steps to getting started with your sound level meter are in the manual. Consider this a quick start guide, where we present essential features and tasks for you to start using your new sound level meter.

Sound level meter platform that equips you for any measurement task

With a wide range of room acoustic measurement tasks, VM Acoustics needed a measuring instrument that could server their needs reliably, and which complies with all relevant standards. Enter in B&K Type 2250 sound level meter.

Sound Insulation: Measuring Airborne Sound

Neighbourhood noise issues are both a function of the noisy neighbour and the building’s noise attenuating properties. The lower the sound insulation of the building partition between you and your noisy neighbour, the more likely you are to be disturbed.
