Operation of a MEMS-Microphone Sound-Level-Meter in Dusty Environments

MEMS microphones, such as those used in the Noise Sentry RT line of integrating sound-level meters, have definite advantages compared to traditional electrostatic microphones: They produce a very low-noise, high-quality signal. They are very small. Many of them integrate amplification and digital sampling electronics, thereby providing a digital signal directly. They are manufactured using tightly […]

Low-Cost Windows Tablets Bolster Sentry-Series Instruments

Since very early on, Convergence Instruments has designed instruments with a minimalist, even non-existent, built-in user interface. This approach provides a much lower cost instrument, or one with better performance at the same price-point. A full-featured user-interface is implemented through a connection to a personal computer, which provides a very rich graphical display and more […]

Sound Level Meter Data Logger

New software for Noise Sentry RT a new generation of smart integrating sound-level meter/datalogger

The newly developed BigDisplay software is an application dedicated to hospitals, libraries, or any public areas where the noise level is a concern. When the level gets past an adjustable threshold displays on a large screen a pictogram’s asking the public to reduce the ambient noise level. As all Convergence Instruments software’s this application is free and can […]
