Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

Handheld Sound Measurement | WAVES Articles

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.

New BK Connect Applets for post-processing

With our release of the BK Connect® 2021, new post-processing applets were introduced, allowing users to cost-effectively perform advanced analyses on measurement recordings made with HBK’s hand-held analyzers. Each applet is tailored for a specific analysis need, such as FFT Analysis, Loudness and Overall Analysis, and Order Analysis.

Motorcycle exhaust noise measurements

Effective and reliable motorcycle exhaust noise measurementsType 2245 sound level meter from Brüel & Kjær makes measurements significantly easier.

Noise protection measurably simplified

Noise measurement is easier than ever using the Type 2245 sound level meter from Brüel & Kjær.

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 Power and Sound Pressure Explained

Sound power is the total airborne sound energy radiated by a sound source per unit of time. Sound pressure, on the other hand, is the result of sound sources radiating sound energy that is transferred into a specific acoustical environment and measured at a specific location. Sound power is the cause, and sound pressure is the effect.

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?

How Loud is a Camera Shutter?

How loud is a camera? Or more specifically, how loud is a camera shutter when we take a photo? And has anything changed from old vintage medium format cameras through to today’s digital cameras?

Historical Milestones of a Sound Level Meter

This article looks at the history and evolution of sound level meters, delving into history, and the new trends that are shaping their future. Many of the technological developments that have changed society, are now finding their way into the world of sound measurement.

How Weather Effects On Noise Measurements

The customer wants the report by next week and you are waiting for suitable weather conditions before you can measure. In practice, meteorology requirements are often difficult to fulfil, particularly if you have a deadline. It is no wonder that weather requirements are sometimes glossed over.

B&K 2245 - From Drawing Board to Release

From the release of the world’s first transistorized and hand-held sound level meter, through the early digital and modular software-driven sound level meters to the touchscreen-driven Types 2250 and 2270 of today, Brüel & Kjær has been consistently at the forefront of sound level meter development.

A Peak Under the Hood of a Type 2250 Sound Level Meter

In this interactive graphic, we invite you to take a peek under the hood of B&K Type 2250 sound level meter, and explore some of its most interesting features and design details.

Lifetime Cost Of A Sound Level Meter

So you’re looking to purchase a new class 1 sound level meter. There are many options out there, and many factors to take into consideration – the initial price tag is only one aspect of the lifetime cost of ownership. This guide is designed to help you lay a basis for fair price comparison based on your needs.

Noise Monitoring for Optimal Mill Operation

Mining companies around the world continue to face the challenge of increasing productivity and reducing downtime. As part of its SAG mill control system, Manta Controls developed the Manta Mic: a robust and reliable acoustic analyser that prevents mill damage.

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.
