Tyco offer a wide range of Noise Measurement equipment.

Pulsar Nova

The Nova range of high performance sound level meters combines advanced technology noise measurement methods with ease of use and durability.

The Nova range consists of six powerful sound level meters. These differ from other sound level meters, as they offer the user the unique opportunity to add features either immediately or at a later date so that the instruments will always be suitable for their requirements.

Standard Measurement Kits

Instruments are usually supplied as part of a noise measurement kit which contains everything required to take noise measurements.

• Nova sound level meter
• Acoustic calibrator
• Windshield
• Batteries
• Hard Kit Case
• 7 year warranty
• Calibration certificates
• Pulsar AnalyzerPlus software
• Download cable

Outdoor Measurement Kits

Both Class 1 and Class 2 instruments have a removeable preamplifier which enables the instruments to be used with microphone extensioun cables. These outdoor measurement kits transform the hand held instrument into a longer term, outdoor monitoring system.


AnalyzerPlus allows the user to download their measurement data onto a PC or laptop for analysis and to create a variety of reports.

Model 14 Digital Sound Level Meter

The Model 14 is an entry-level sound level meter for general purpose use whilst meeting the requirements of IEC 61672 Class 2.

It is also an ideal low-cost instrument for those applications where a sound level meter can be useful but a high specification instrument would be too expensive.

Noise levels can be checked quickly and simply, through the instrument’s large and easy-to-read display, which shows the Sound Level (SPL) with the standard dB(A) frequency weighting. Also included is the dB(C) frequency weighting.

A maximum hold function allows the unit to freeze the display showing the highest level measured. This can be used where the allowable level is given in terms of a maximum (LAFmax or LCFmax).

The ‘A’ weighting filter is the internationally recognised method of replicating the response of the human ear to noise, making the Model 14 the ideal tool for basic noise risk assessments.

The instrument can be calibrated for compliance using the Model 106 Acoustic Calibrator, when used for industrial noise checks.

Two measurement ranges are included in the Model 14, measuring the most typically encountered levels from 35dB(A) to 130dB(A)

The Model 14 is the perfect solution for basic industrial noise surveys and ideal for use in the measurement and checks of vehicle noise, workplace noise, fire alarms, audible warnings systems and during the installation of sound systems.

Model 22 Personal Noise Dosimeter

The Model 22 doseBadge is compact, extremely robust and lightweight. The revolutionary doseBadge is a self-contained noise measurement device that has no cables, display or controls, making it an ideal solution for noise dosimetry because units can’t be tampered with during measurement.

doseBadges communicate with an infra-red Reader Unit - similar technology to a television remote control. The Reader Unit controls the doseBadge to program, calibrate, start/stop, download and store measurements.

All key measurement parameters can be viewed on the large clear backlit screen of the Reader Unit, which also displays a time history graph of workers’ daily noise exposure.

The doseBadge is rechargable, making it more economical and designed to run for an entire shift. The Reader Unit is used to setup and calibrate one or more doseBadges prior to use and also to start the measurement. The doseBadge unit logs and stores data throughout the period of measurement and a blue indicator shows when the unit is running. At the end of the measurement, data is downloaded from the doseBadge into the Reader Unit through the infra-red link with the Reader Unit displaying the measurement data.

The Model 22 doseBadge systems are ideal for most applications as the preferred method of calculating personal daily noise exposures to ensure compliance with International Safety Legislation.

It is especially suitable for applications where workers are regularly moving from location to location, working with moving machinery in difficult to reach areas, vehicle cabins, shift work or with unpredictable work patterns.

PulsarSafeEar Noise Warning System

In environments where the wearing of hearing protection (PPE) may not be required at all times, the PulsarSafeEar will inform employees when PPE is required and also when it can be removed safely.

PulsarSafeEar can also be used in quiet locations such as schools, hospitals and libraries to indicate when noise levels must be kept down. By setting the PulsarSafeEar to trigger at a lower level ensures that noise levels in quiet environments stay within acceptable levels.

Installation is simple - Select the trigger level and connect the power supply to the unit. When the noise level measured by the microphone reaches this level, the sign will illuminate and show the warning.

The unit can also be set to keep the warning illuminated for up to 30 seconds after the level has fallen back below the trigger level. This removed the sudden on-off indication that traditional noise warning signs often produce. The PulsarSafeEar eliminates confusion as to when hearing protection (PPE) should be worn.

The sound level chosen for the trigger point can be set using the simple level selection at the back of the unit.

Remote Display Units

The PulsarSafeEar is also available as a Remote Display Unit which is controlled by a Master PulsarSafeEar Unit. A simple cable from the Master up to 3 remote units can be daisy-chained together so that an area of up to 30 meters can be covered.

Record and Store with PulsarSafeEar Data Logging Software

The PulsarSafeEar can be upgraded to become a data logging unit by adding the Data Logger and USB software. The Data Logger simply plugs into the PulsarSafeEar and can record noise levels over long periods of time. The Data Logger can be programmed to start recording at a specific time and date and run, for example, over an 8 hour shift. When the Data Logger is plugged into a PC the software will display a graph of the recorded noise levels and allow the data to be printed, exported and annotated for reference.
