Who is this article for?

ANOMS administrators who want to understand the relationship between RMTs and Locations.

Administrator access to the ANOMS Noise Analyst Workbench is required.

This article explains how ANOMS models noise monitoring equipment and the places where that equipment is installed.

Understanding what an RMT is

RMTs (Remote Monitoring Terminals, also called noise monitoring terminals or NMTs) are the actual pieces of measurement hardware used to collect noise data. ANOMS supports a variety of analyser types, including EMU, Smart Mic, LD870, BK4435 and BK3639 units.

There are two kinds of RMT:

• Fixed RMTs are installed permanently at one Location
• Portable RMTs can be set up at various Locations at different times

Understanding what a Location is

A Location is the actual place where a noise monitor can be installed or set up, identified by a longitude and latitude point. A Location may or may not have an RMT assigned, depending on whether it uses fixed or portable measurement equipment.

Understanding why RMT IDs and Location IDs are separate

ANOMS identifies Locations and RMTs by unique ID numbers. For fixed noise monitors, the Location ID and RMT ID are usually the same. For portable noise monitors they differ, because the same RMT (the physical equipment) may be used at several Locations.

The reason for assigning Location ID numbers separately from RMT ID numbers is to keep portable measurement data identified with where it was measured, not with the particular piece of hardware it was measured with.

Note: Both RMTs and Locations are created and maintained in the RMT Editor. See the article Using the RMT Editor.
