Environmental noise monitoring helps your site stay compliant and at safe levels for staff and the local community
Environmental noise can be a challenge, affecting staff working at your site, local communities and wildlife, and, left unchecked, noise levels can lead to regulatory issues, community dissatisfaction, and a disrupted environment.
Noise and Weather Monitoring Ltd combines world-class technology from Norsonic, with expert advice and knowledge of New Zealand regulations and conditions to help you take regular and accurate environmental noise measurements.
Our team works with clients in a range of industries including infrastructure such as road building and civil construction, transport hubs including airport and shipping ports, motor racing, quarries, and energy generation. As well as outdoor boundary noise monitoring we can also provide acoustic measurement equipment for inside buildings if required.
Why is environment noise monitoring important?
Environmental noise monitoring allows you to measure and analyse noise levels in specific areas such as around the boundary of your site or high-traffic areas. It helps landowners, businesses and organisations to determine issues such as:
- Whether noise from areas like construction sites, industrial sites or transport hubs is too loud for local communities.
- Whether the noise levels on site are safe for workers.
- Whether noise emitted from a site complies with regulatory standards.
- Whether complaints from neighbours are valid and need to be remedied.
Having up-to-date and accurate data on noise levels allows you to quickly diagnose and deal with any issues.
Advanced equipment ensures accurate and detailed results
There is little point in monitoring sound levels if the equipment you use produces results that are too generic or inaccurate. At Noise and Weather Monitoring Ltd, we use world-class Norsonic equipment to give you superior results and ensure compliance with New Zealand standards.
The benefits of our outdoor noise monitors which use the Norsonic Nor145 class 1 sound level meter, and the Norsonic Nor1216 heated outdoor microphone include:
Constant measurement
The Noise monitoring station measures decibel levels in real time, logging the precise level ten times per second. This log can include for example: LAeq, LAmax, LAmin, LA10, LA50, LA90, LA95, 1/3 octaves, wind direction, wind velocity, temperature, rainfall. Also, event based audio and images can also be captured.
Precise measurements & categorisation
Separate noise from your operations or site from environmental noise such as wind to ensure accurate records. With the addition of noise compass you can get even more accurate directional data with sources being automatically categorised.
Self contained power
Noise monitoring stations can be self powered with a battery or solar panel. This means you are not reliant on mains power. The equipment also includes its own internal 4G modem to send data to storage. We recommend regular servicing to ensure the battery or solar panels and modem are in good working order.
Our full service ensures accurate installation
At Noise and Weather Monitoring Ltd, we offer a full service for your environmental noise monitoring.

Acoustic measurement equipment ranges from cheap mobile apps that provide minimal detail and basic noise monitors with low performance which may not capture everything to high-precision devices used for professional noise monitoring, These collect noise levels constantly and can include frequency analysis. Selecting the right tool for the job isn’t always easy, We’ll freely share our experience to help you make the best choice.
Our process includes:
- Identifying site-specific requirements and goals.
- Confirming regulatory requirements with local authorities.
- Selecting the appropriate equipment and installation locations, potentially including solar power, camera, and weather monitoring to complement the noise measurements.
- Providing cost estimates and scheduling installation.
- Setting up online data access and training your team.
- Ongoing support to maximize the effectiveness of your monitoring system.
Noise data is continuously recorded, capturing every second of every day. Reports can be generated automatically based on your requirements or accessed anytime via our secure online platform. Data is securely uploaded to the NorCloud website where it can be accessed by approved individuals, which may include your usual acoustics engineer. Real-time and historical data can be viewed through the platform. For more details see www.noisecompass.com
