What Is a Sound Level Meter?
What Is a Sound Level Meter?
A sound level meter is a measuring instrument designed to measure sound levels in a standardised way. Commonly referred to as a sound meter, noise meter, decibel meter, or sound pressure level (SPL) meter, a sound level meter is designed to respond to sound in approximately the same way as the human ear.
The purpose of a sound level meter is to give objective, reproducible measurements of sound pressure levels (SPL).

Meter work?
How does a Sound Level
Meter work?
A sound level meter primarily consists of a microphone, a preamplifier, a signal processing unit, and a display. The best microphone type for these devices is a condenser microphone, as it offers precision and reliability. It converts sound into a low-level electrical signal, which the preamplifier boosts before processing. Signal processing applies frequency and time weightings to the signal, in accordance with international standards like IEC 61672-1.

Measurement Applications
for sound level meters
Sound level meters and analysers are used to measure and manage noise from a variety of sources. Often employed in environmental noise assessments, such as industrial plants, road and rail traffic, and construction works.
In urban environments, noise pollution can directly impact the health of people in these affected areas. To ensure noise regulations are followed, sound levels are measured from a variety of sources, such as sports events, outdoor concerts, residential and commercial neighbourhoods, etc. Each sound source is defined and scored based on a range of characteristics, which determine if standards are complied with.
Building Acoustics Partner
Sound Level Meters play an essential role in building acoustics, giving engineers the means to measure acoustic properties that are critical in ensuring a structure is up to standard for its primary function.
The 2255 with Building Acoustics Partner allows for fast and simple measurement of a range of parameters, including impact sound insulation, façade sound insulation, etc.
With both Mobile and PC software, project schedules can be created in the office, saved to the SLM and carried out via the mobile app, ensuring that no measurement points are missed.
The PC software is also capable of automatic report generation, conforming to the test standards used, greatly reducing time requirements.
Product Noise Partner
Together with an HBK 2255 sound level meter, Product Noise Partner is a complete, focused toolset for product noise testing – from sound power determination according to international standards, to verifying safe noise emissions from toys according to EN 71-1. HBK 2255 sound level meter with the Product Noise Partner concept combines ease of use and operational simplicity with a complete product noise measurement toolset so that the system’s potential can be harnessed by any user, from novice to acoustics specialist.
The Product Noise Partner app measures sound power levels for machinery and equipment such as household appliances in order to comply with national and international regulations and help promote a safe and healthier environment.
Work Noise Partner
Workers who spend excessive amounts of time around noisy machinery can face serious health issues, such as hearing loss; health and safety standards are in place to ensure suitable protective gear is in place to minimise the risk of this.
The Work Noise Partner Suite provides a complete toolset for measuring occupational noise-related concerns, such as noise exposure surveys and risk mitigation for noise-induced hearing loss.
