• LAeq, Ln, LMax, LMin
  
• Audio recording

Environmental conditions can significantly impact the accuracy of sound level measurements, particularly when conducting assessments in outdoor environments, so this is where an Outdoor Environmental Noise Kit can help you. The kit provides a fully weather-protected system for outdoor noise measurement to protect your sound level meter and microphone from harsh weather conditions, ensuring reliable and accurate readings in any environment for up to 1 week.

The Outdoor Environmental Noise Measurement Kit includes:

• Your choice of Class 1 Optimus+ Green Sound Level Meter designed specifically for environmental noise measurement
• A protective case to shield your equipment from rain, wind and other elements
• A protective cover for the microphone, which reduces wind noise and other unwanted sounds
• Your choice of batteries or an external power supply for operation over extended periods of time

The environmental noise measurement kits provide weather protection for the sound level meter and the microphone, allowing for noise measurements over long periods where the equipment is unattended and making it ideal for environmental noise monitoring. This allows effective, accurate noise measurements to be made where it’s not possible to have staff on-site with the equipment at all times.

• Robust and secure case protects the Optimus Sound Level Meter
• Carry out noise monitoring even when you can't be on site
• Calibrated, accurate measurement data lets you make more effective decisions
• Download information into NoiseTools directly or remotely, giving you access to your data when you need it

Construction noise monitoring involves the measurement and assessment of noise generated by construction activities. It is essential for evaluating and managing the potential impact of construction noise on nearby communities, workers, and the environment.

For construction sites, receiving real-time alerts when pre-set noise limits have been exceeded, or are close to being exceeded, can be an effective noise control process. As this information can be provided in real-time (either to staff on-site or to a remote office) it can enable site managers to investigate the source of the noise and to take quick, effective actions to remedy the issue. The MyCirrus Notification App provides real-time notifications and alerts, allowing for effective control of construction site noise levels.

• Configure triggers in the Optimus Green to match site noise limits
• Stay informed as noise levels approach those limits by utilising triggers and notifications
• Receive real-time alerts through MyCirrus direct to the Notifications App on your phone or tablet

For boundary noise monitoring, measurements when noise sources are not operating (over a weekend for example) can be critical in determining if there is significant impact when the site is in operation.

By using an environmental noise measurement kit, data can be gathered over extended periods when noise sources are and are not operating, allowing more robust assessments to be made.

• Measure noise levels over long periods to cover both on and off conditions for the noise sources under investigation without having to be with the equipment
• Gather accurate, informative noise data regardless of the weather conditions or the environment that the equipment needs to be left in
• Configure triggers in the Optimus Green Sound Level Meter to activate when known noise sources are active, whether you're on site or not
• Receive real-time notifications when triggers are activated and store high-resolution audio recordings, allowing you to determine the source and type of noise being measured
• Quickly identify and highlight noise sources in the NoiseTools software to determine if penalties should be applied, creating reports and exporting data for analysis in other software packages

Logging data over long periods before, during and after the construction of a wind farm can often be the only way to effectively judge the impact of operations and the environmental noise measurement kits can assist in this task.

The advanced triggers in the Optimus sound level meters can provide real-time alerts when overall levels or specific frequencies are exceeded as well as when tonal noise is detected.

• Use the power of the Optimus Green Sound Level Meters to log detailed noise data over long periods of time
• Make measurements over long periods by adding external power to the kits from a battery, mains or solar power
• Use the advanced triggers in the Optimus Green to detect tonal or frequency-based noise sources
• Send real-time alerts & notifications to the MyCirrus App when triggers are activated
• Download measurement data without having to visit the equipment using the modem, MyCirrus and the NoiseTools software
