Find out more about our range of sound level meters

We supply a wide range of sound level meters from low-cost digital noise meters suitable for quick noise measurements to Class 1 and Class 2 instruments, which are ideal for legally compliant occupational noise measurements and more detailed noise frequency analysis as well as environmental noise monitoring.

Class 1 (Type 1) & Class 2 (Type 2) Sound Level Meters for all applications including:
  • Type Approved meters to international standards IEC 61672-1:2002 and IEC 61672-2:2003 from the PTB
  • Data Logging sound pressure level meters (spl meter) with up to 32GB of memory (enough for 1 month of noise and audio measurements)
  • Integrating averaging sound pressure level meters for occupational noise & workplace noise exposure measurements that measure LAeq / Leq as well as Cpeak
  • Decibel Level Meters with a dynamic measurement range (frequency range) from 20dB(A) – 140dB(A), C-peak 143dB(C)
  • Octave Band meters for octave band analysis and the selection of hearing PPE & Noise Control
  • High-performance Decibel Meters with real-time 1:1 and 1:3 Octave Bands and Audio Recording for Environmental Noise, or for measuring more complex sound
  • Time weighting (fast, slow and impulse) and frequency weighting (A, C and Z weightings)
  • Noise Frequency Real-time Analyser for detailed acoustic analysis
  • A simple low-cost meter for basic noise testing applications and for sound level indication for things like fire alarms.
Noise measurement kits

All of the sound level meters and noise meters in Pulsar Instruments range can be supplied as a complete noise measurement kit containing db meter, acoustic calibrator, windshield, and other essential accessories. They come with valid calibration certificates and a warranty. The Pulsar Nova range can also be used with an all-weather outdoor measurement kit that provides protection for the meter and its microphone from the elements and dust, allowing sound intensity measurements to be made over long periods in a variety of environments.

The Noise at Work Regulations state that an integrating sound level meter (or SLM) is required for occupational noise assessments. For most Health and Safety applications, for example, including Noise Risk Assessments in the workplace, an integrating Class 2 meter is all that is required. These are meters that measure the LAeq (Equivalent Continuous Sound Level, also referred to as Leq) LAeq is the preferred way of measuring varying sound level over time, the resulting measurement is a single decibel value which is used in occupational noise assessments to determine the noise levels of an activity over time, or the noise levels a person (or persons) are exposed to.

You can also use a Class 1 meter. This is has higher precision than Class 2 and it is often used for sound level measurements of environmental noise and for laboratory applications, although you can use it for most other acoustic measurement applications such as industrial and construction noise assessments. The tolerance in each frequency is much tighter on Class 1 than on a Class 2 meter. Most British Standards call for a Class 1, but occupational noise measurements only require Class 2.

Yes. There are different types of calibration. You need to field calibrate your meter before and after every set of measurements with an acoustic calibrator. You need to have a periodic calibrator (factory calibration) at least every two years, however, Pulsar recommends you return your instrument annually to us for recalibration and in return, we will extend your product warranty up to 7 years. All instruments leave Pulsar Instruments professionally calibrated and are supplied with a valid calibration certificate to international standards. Pulsar can also supply your meters as UKAS calibrated which is the highest level of calibration you can receive (extra charges apply for this).

Yes. We advise you use a windshield to protect the microphone from dust and environmental conditions when you are conducting a noise level measurement inside and outdoors. When you buy a sound meter from us a windshield is supplied as standard. If you lose it or it gets damaged you can purchase a replacement.

Our meters can be used for a range of applications for measuring noise levels:

  • Noise at work
  • Occupational and industrial hygiene (to guard against hearing loss risk)
  • Environmental noise measurement
  • Boundary noise measurement
  • Machinery noise testing
  • Vehicle noise testing
  • Entertainment noise measurement
  • Community noise
  • Sound exposure

A decibel dB meter fitted with Octave Band Filters can split the audible spectrum into smaller bands that identify the frequency content of the sound. If you are taking environmental noise measurements we recommend you buy a meter with at least 1:1 octave band filters. If you are measuring occupational noise they are not necessary, however, some people like to use them to identify more accurately the frequency of noise and the levels of hearing protection to prescribe. With the Pulsar Nova range of instruments, you can buy a meter with 1:1 octave band filters (Models 45 and 46 have it as standard), or you can choose to upgrade to this option at a later date. If you have this option, the Pulsar AnalyzerPlus software will supply a range of options of hearing PPE based on the octave frequency content of the noise you measure.
