Sound is what we hear. Noise is unwanted sound.
Noise perception is subjective. Factors such as the listener and the circumstances (magnitude, characteristics, duration, and time of occurrence) may affect one`s subjective impression of the noise.

Preventing Noise-Induced Hearing Loss
Noise-induced hearing loss is preventable. Exposure to harmful noise can cause irreversible damage to an individual’s hearing. The solution is often a combination of steps starting with measuring the level of sound and aided by the use of hearing protection. We are normaly faced with
Environmental Noise
Noise at Work
Noise Nuisance

We provide innovative instruments that will ultimately save people’s hearing from being irreparably damaged, and prevent them from developing other serious conditions associated with hearing loss.

Sound Level Meters

The Series 308/310 basic sound level meters
Get the basic noise data you need easily and quickly.

The Series 308/310 are basic sound level meters that are perfect when you need basic noise information, capable of measuring the maximum sound level (LMax) and the sound pressure level (SPL).

The Series 308/310 sound level meters provide an entry level for noise measurement across multiple sectors, and meets current international standards for noise measurement instrumentation.

Both variants provide the SPL and LMax readings, which can help you determine how loud something/somewhere is without overcomplicating the data with other acoustic information. Both variations can also measure different frequency weightings, which provides more detailed and accurate data than many other basic sound level meters on the market.

The new high-performance doseBadge5 wireless dosimeter we offer that allows you to make compatible work noise exposure measurements, apply effective control measures and ensure that workers are not exposed to noise levels that will endanger their hearing.
The doseBadge5 is powerful and simple to use, ensuring that you can collect reliable and reliable information that can be used effectively to assess professional noise and include all the unique features of the original dispenser, such as no control, cables or screens in a row from new features and capabilities.
In addition to the 4 independent channels or integrators (which can be configured to meet any combination of regulations, standards, or instructions), doseBadge5 now provides octave real-time analysis across the measurement, and when combined with NoiseTools software, individual sources of noise, make the choice of hearing protection quicker, simpler and more effective.
