HBK launches new sound level meter with Building Acoustics Partner

To help those involved in architectural and environmental acoustics, sound and vibration expert Hottinger Brüel & Kjær (HBK) has designed the HBK 2255 Sound Level Meter, which provides a complete measurement solution.

The HBK 2255 Sound Level Meter is ideal for any sound measurement task, from measuring the environmental noise emissions of a new roadway, to verifying sound insulation performance between apartments.

Weighing just 400 grams, the lightweight sound level meter has a rubberized body for a secure grip and places the measurement controls right under the user’s thumb. It has Wi-Fi® and Bluetooth® built in and works with specially created mobile and PC apps, providing an entirely new level of efficiency and control. It can also operate as a stand-alone sound measurement device without an app.

HBK 2255 forms part of a new building acoustics measurement solution from HBK. The Building Acoustics Partner app provides full workflow support and wireless remote control for sound insulation measurements. The solution is completed with a HBK 2755 Smart Power Amplifier that enables wireless remote control of the sound source in a compact, robust and lightweight package.
