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 Optimus+ Red noise at work sound level meter makes noise level measurements incredibly easy and straightforward, 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, 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 again. 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.

The Optimus+ Yellow is a range of basic sound level meters built to international standards (IEC 61672) and available as either Class 1 or Class 2 sound level meters. The range is the entry-point for Cirrus Research's well-renowned Optimus+ range. The Optimus+ Yellow noise level meter is capable of measuring the maximum noise level during a session, and provides simple and easy-to-understand data, including frequency weightings and time history. The Optimus+ Yellow is a state-of-the-art noise level meter that has been designed by the engineers at Cirrus Research to meet the very latest international standards in sound measuring and monitoring.

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 Original doseBadge is the original wireless personal noise dosimeter. It is the ideal tool to carry out occupational and industrial hygiene noise measurements and provides a unique solution for these applications. Combining an innovative design with simple, robust and reliable operation, the Original doseBadge weighs only 51g/1.8oz. With no cables, controls or displays, the Original doseBadge can be worn in areas where there is a risk of damaging traditional style units or where there is a risk of tampering. Designed and manufactured by Cirrus Research plc, the doseBadge is an innovative instrument that is ideal for measuring and assessing the noise exposure of workers and employees across all locations.

The Advanced doseBadge5 is a high performance wireless noise dosimeter that allows you to make compliant occupational noise exposure measurements, put into place effective control measures and ensure that workers are not exposed to noise levels that will put their hearing at risk. The Advanced doseBadge5 is powerful yet simple-to-use ensuring that you can gather robust, reliable information that can be used effectively for the assessment of occupational noise exposures and includes all of the unique features of the original doseBadge such as no controls, cables or displays with a range of new functions and features.

Quantum Indoor is a powerful noise monitoring solution with built-in cloud connectivity, perfectly suited for unattended indoor noise monitoring across a range of applications. Quantum Indoor can be used for: long-term occupational noise monitoring; identifying the source and type of noise that is occuring; and highlighting where noise control measures are required. Quantum Indoor is the perfect complementary solution to any existing noise monitoring regime as it offers all the freedom and benefits that come with remote outdoor noise monitors, but specifically designed for an indoor application. It provides a constant ear to the ground, constantly capturing and storing noise data on the MyCirrus cloud platform for you to access whenever you need it. You can also set up comprehensive event-based triggers to capture audio recordings and send alerts to users, allowing you to react to and control noise events in real-time.

The iconic SoundSign from Cirrus Research is an easy-to-install noise-activated warning sign that can be used in environments where there is a need to clearly warn or indicate when a preset noise level has been reached and/or exceeded. The SoundSign uses bright LEDs to display a message when the noise level you select has been breached; the level can range from 40dB(A) to 114dB(A). The SoundSign is absolutely perfect for environments such as factories and workshops as it can serve as a visual alert or reminder for your staff to wear their hearing protection. It's also great for quiet environments like schools, hospitals and libraries as it will act as a silent reminder for people to keep the noise levels down. Available in four distinct designs and in multiple languages, the SoundSign can be used in any environment, almost anywhere in the world.
