U.S. Army Seeks Lab Standard Microphone System and Calibration Services for Acoustics Lab

The U.S. Army Test, Measurement, and Diagnostic Equipment Activity (USATA) is seeking to procure a Lab Standard Microphone System or equivalent to replace damaged laboratory microphones essential for acoustics calibration. - Government Buyer: - U.S. Army TMDE Activity (USATA), under Army Contracting Command-Redstone Arsenal (ACC-RSA) - OEMs and Vendors: - No OEMs are explicitly named in the solicitation, but the referenced models (4180PTO, 4160PTO) are strongly associated with Brüel & Kjær (Hottinger Brüel & Kjær Inc.) - Interested vendors include PB&J Partners, Silver State Medical Supply LLC, and Hottinger Brüel & Kjær Inc. - Products/Services Requested: - 1x 4180PTO 1/2" Calibration Condenser Microphone, laboratory standard (Part Number: 4180PTO) - 1x 4160PTO 1" Laboratory Standard Pressure Microphone, 200V Polarization (Part Number: 4160PTO) - 1x AO-0087-D-012 Cable, coax single screen, BNC (M) to BNC (M), 1.2m (Part Number: AO-0087-D-012) - 1x ET-2014-W-002 Primary DPLA Microphone Calibration for 4180 (Part Number: ET-2014-W-002) - 1x ET-2014-W-001 Primary DPLA Microphone Calibration for 4160 (Part Number: ET-2014-W-001) - 2x Shipping - Notable Requirements: - The microphones are critical for maintaining accredited calibration parameters in the Acoustics Lab; replacement is necessary to prevent lab shutdown - Calibration services must cover specific frequency ranges (10Hz–25kHz for 4180, 2Hz–10kHz for 4160) - Calibration results must comply with IEC 61094-2:2009/AMD1:2022 - Reciprocity calibration requires three microphones of the same model - Delivery required within 30 days after order - Estimated contract value is $42,085

Description

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):

1.0 Requirements:

4180—PTO   1/2" Calibration Condenser Microphone, laboratory standard.                               Qty: 1

ET-2014-W-002- Primary DPLA Microphone Calibration 1/3 octave frequencies 10Hz to 25 kHz for type 4180                                                                                                                                                                        Qty: 1

4160—PTO      1" Laboratory Standard Pressure Microphone, 200V Polarization.                                  Qty: 1

ET-2014-W-001-Primary DPLA Microphone Calibration 1/3 octave frequencies 2Hz to 10kHz for type 4160. Results calculated according to IEC 61094-2:2009/AMD1:2022                                                        Qty:1

AO-0087-D-012- Cable, coax single screen, BNC (M) to BNC (M), 1,2m (4.0ft), max.+85°C (185°F)      Qty:1
