Anaheim S665 - Class 1 Integrating Sound Analyzer Meter

Model S665 is a Class 1 Integrating Sound Analyzer. A handheld real-time analyzer that performs integrated measurement and statistical analysis on noise or other electrical signals. Additionally it includes their frequency spectrum and amplitude, 1/1 OTC and 1/3 OTC value through digital signal processing technology. This analyzer can be widely used in various fields such as environmental protection, labor hygiene, research and teaching, industrial enterprise, noise measuring and testing etc. It can perform environmental noise measurement, machinery noise analysis, sound power level measurement, building acoustics and aircraft noise measurement.

Anaheim Scientific Model S665 is a Class 1 Sound Analyzer Meter. This superior Class 1 Sound Analyzer offers a wider frequency range and a tighter tolerance over a Class 2 unit. This integrating meter sums the frequency-weighted noise to give sound exposure levels. Use the S665 for noise pollution studies for the monitoring and quantifying of almost any noise, i.e. industrial, environmental or aircraft.

Model S665 meets the current International standard for sound level meter performance IEC 61672-1:2002 Class 1. This standard directs the inclusion of an A-frequency-weighting filter plus the addition of C and Z (zero) frequency weightings.

An integrating sound level meter sums the frequency weighted noise energy over a measurement period of time to display the sound exposure and is generally described in decibels (Sound Exposure Level or SEL).

Applications

• Environmental Monitoring for: 1) total noise exposure along federally funded highways, 2) For all civil aircraft noise measurements A-frequency-weighting is used as mandated by the ISO and ICOA standards, 3) fixed airport noise monitoring systems.
• To confirm noise guidelines established for sound transmission by national, state or provincial and municipal levels of government.
• Maintain sound levels at work for the protection of workers against noise-induced deafness. Chronic exposure to noise could cause noise-induced hearing loss.
• Most city ordinances prohibit sound above a certain threshold intensity from trespassing over property lines at night.
• Construction noise, power equipment of individuals and unmuffled industrial noise penetrating residential areas.
• Follow stringent building codes with requirements of acoustical analysis, in order to protect building occupants from (a) exterior noise sources and (b) sound generated within the building itself.
• The U.S. Occupational Safety and Health Administration has established maximum noise levels for occupational exposure, beyond which mitigation measures or personal protective equipment is required.
