The U.S. Army TMDE Activity (USATA) has a requirement to implement a brand name purchase of one (1) Lab Standard Microphone System model or equivalent that will be a suitable replacement for the 4180/4160 Microphones are the main standard for the Acoustics Lab. Three standards have been lost due to damage. Reciprocity calibration requires three microphones of the same model to function appropriately. APSL needs to replace these standards to prevent a potential shutdown of the acoustics laboratory. All accredited parameters within the acoustics lab are tied to these laboratory grade Microphones. The Lab Standard Microphone System shall include the following specifications or equivalent (if not brand name): Requirements: 4180PTO 1/2" Calibration Condenser Microphone, laboratory standard.
