GAO’s environmental sound level meters & calibrators have the following functions:

• Measuring sound pressure levels: GAO's environmental sound level meters & calibrators are designed to measure the sound pressure level in decibels (db.) using a microphone. They can measure sound levels over a wide range of frequencies and amplitudes and can provide various types of weighting and filtering to account for the different ways that humans perceive sound.
• Analyzing sound: GAO's environmental sound level meters & calibrators can analyze various sound parameters, including frequency, amplitude, and duration, and provide data on the statistical distribution of sound levels over time.
• Calibrating sound level meters: Our environmental sound level meters & calibrators are used to calibrate sound level meters to ensure their accuracy. They generate a known sound level and frequency, which is used to adjust the sensitivity of the sound level meter.
• Storing and logging data: Our environmental sound level meters & calibrators can store and log sound level measurements, allowing for later analysis and reporting of the data.
• Displaying real-time data: GAO’s environmental sound level meters & calibrators have a real-time display that shows the current sound level, as well as other parameters, such as frequency weighting and time weighting.
• Providing audio output: Our environmental sound level meters & calibrators have a built-in speaker or audio output jack, which can be used to listen to the sound being measured.

GAO’s environmental sound level meters & calibrators are rugged, versatile and precision measurement instruments. They comply with applicable industry standards such as ANSI (American National Standards Institute) S1.4-2014, IEC (Industrial Educational Cooperative) 61672-1:2013, ANSI S1.40-1984, IEC 60942:2017, and ISO 9614-1:1993.

GAO’s environmental sound level meters & calibrators have the following applications:

• Workplace safety: Our environmental sound level meters & calibrators are used to measure and monitor noise levels in workplaces to ensure compliance with safety regulations and to prevent hearing damage to workers.
• Environmental noise monitoring: GAO’s environmental sound level meters & calibrators are used to monitor noise levels in the environment, such as in residential areas, near transportation routes, and around construction sites, to assess the impact of noise on the community.
• Product testing: Our environmental sound level meters & calibrators are used in product testing to measure the sound output of various devices, such as home appliances, electronic gadgets, and automotive products.
• Acoustics research: GAO’s environmental sound level meters & calibrators are used in acoustics research to measure sound levels and analyze sound characteristics, such as frequency, amplitude, and duration.
• Music production: Our environmental sound level meters & calibrators are used in music production to ensure that sound levels are properly calibrated and to measure the levels of different sound components, such as bass, midrange, and treble.

Our environmental sound level meters & calibrators can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
