Marine Yacht Boat Engine Sound Insulation is done to prevent you from being exposed to the sounds generated in the engine during your boat trips. People prefer boats to spend a quiet and peaceful time. However, since the high level of noise produced by boat engines is disturbing, sound insulation is inevitable. Boat Engine Sound insulation helps eliminate the noise created easily.

We’re proud to announce the launch of the new GPS-enabled Optimus+ sound level meter, designed to make environmental noise monitoring easier and more effective than ever before. The Optimus+ GPS builds on the incredible technology of Cirrus’ iconic Optimus range, by providing highly accurate location data for every measurement that’s taken. Optimus+ GPS automatically stores location data with each reading, which can be analysed in our licence-free data reporting software, NoiseTools. There’s no need to purchase a whole new noise measurement instrument to benefit from the GPS functionality, you can simply purchase the module and add it to your existing Optimus+ Red or Green device. It’s also available as a full sound level meter kit. With optimised battery life, the Optimus+ GPS is perfect for taking environmental noise measurements. The industry-leading time to first fix means that it is easier and faster than ever before to connect the module to a GPS signal.

The CR:308 and CR:310 are basic sound level meters that are perfect when you need simple noise information. Both meters are capable of measuring the maximum sound level (LMax) and the sound pressure level (SPL). Both the CR:308 and CR:310 are used for simple sound measuring applications, such as alarm testing, spot checks, and very basic occupational noise checks. The Cirrus Research CR:308 and CR:310 sound level meters provide an entry level for noise measurement across multiple sectors, and meet current international standards for noise measurement instrumentation. Both variants provide the sound pressure level (SPL) and maximum sound level (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 available on the market.

The Optimus Green sound level meter has been specifically designed as an environmental noise meter and is perfect for measuring and monitoring exposure to noise pollution and environmental noise sources. Available as either a Class 2 or Class 1 sound level meter, built to IEC 61672, the Optimus+ Green environmental noise meter provides everything you need to measure both occupational and environmental noise to the fullest extent. Capturing the full range of sound parameters simultaneously, there's no other noise measuring instrument you need to measure and monitor exposure to environmental noise.

The top-of-the-range Optimus+ Green has been specifically designed as an environmental noise meter and is perfect for measuring and monitoring exposure to noise pollution and environmental noise sources, including construction sites, windfarms and industrial operations. Available as either a Class 2 or Class 1 sound level meter, built to IEC 61672, the Optimus+ Green environmental noise meter provides everything you need to measure both occupational and environmental noise, to the fullest extent. Capturing the full range of sound parameters simultaneously, there’s no other noise measuring instrument you need to measure and monitor exposure to environmental noise.

Measuring noise at work doesn't need to be a time-consuming task. The Optimus+ Red noise at work sound level meter makes noise level measurements incredibly easy and straightfoward, as it uses advanced digital acoustic technology to save you time while capturing all essential noise level data simultaneously. The instrument captures sound pressure level (SPL), time weighted and frequency weighted values, and octave band data at the press of a single button. You'll never need to worry about missing something or choosing the wrong function: just turn it on, calibrate it, and get measuring! By measuring every parameter you need simultaneously, you can be sure that your occupational noise survey will be comprehensive and robust, providing the level of detail required for making better-informed decisions and reporting to key stakeholders within your organisation.
