Bedrock Class I Acoustic Measuring Instrument

This Bedrock Class I Acoustic Measuring Instrument is an accurate and reliable device suitable for a wide variety of applications. This device is easy to use – it is the instrument of choice whenever precise acoustic measurements are required. It features a Class I / Type I sound level meter (fast, slow, impulse; A/C.Z-weighting, Lew, SEL) conforming to IEC-61672 class 1, ANSI S1.4 Type 1. It features three different modes of STIPA (Speech Transmission Index for Public Address) measuring – a quick screening mode, a pro mode, and an averaging mode.

It also features full direct STI measurements, Speech Level measurements, statistical acoustics, real-time analysis, and much, much more! It has a 20Hz-20KHz frequency range with a dynamic range of 24-124 dB (with included microphone). This device has a full color hi-res TFT touch screen display, along with 32 GB of storage and access to stored data and recorded audio through a high-speed USB 2.0 interface.

What are Class I / Type 1 Acoustics?

Class I (Type 1) acoustics refers to a classification system used for sound level meters and microphones. It is a standard defined by the International Electrotechnical Commission (IEC) in the IEC 61672-1:2013 standard for electroacoustics - sound level meters - Part 1: Specifications. The IEC is an international organization that sets standards for electrical and electronic technologies, including acoustics and sound measurement.

Class I sound level meters are typically used in professional and regulatory applications where high accuracy and precision are essential. These instruments are commonly employed in acoustical engineering, environmental noise monitoring, noise control, and compliance with noise regulations and standards.

In context of alarm systems, ensuring acoustic measurements are up to standards is very important to help ensure the safety of your building and the people in it.
