Lab Standard Microphone System

Request for Information (RFI)

This RFI is issued by the U.S. Army Contracting Command-Redstone, in support of the U.S. Army Test, Measurement, and Diagnostic Equipment Activity (USATA). The purpose is to conduct market research to identify potential sources capable of providing a brand name or equivalent Lab Standard Microphone System. This system is needed as a replacement for damaged 4180/4160 Microphones, which are critical standards for the Acoustics Lab. The loss of these microphones risks a potential shutdown of the lab's operations.

The required Lab Standard Microphone System shall include the following components or their equivalents:

• 4180—PTO 1/2" Calibration Condenser Microphone (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) (Qty: 1)

• AO-0087-D-012- Cable, coax single screen, BNC (M) to BNC (M), 1.2m (4.0ft) (Qty: 1)

• Shipping (Qty: 2)

• NAICS Code: 334310 Audio and Video Equipment Manufacturing

• Classification Code: 5965: Headsets, Handsets, Microphones and Speakers

• Place of Contract Performance: Redstone Arsenal, AL

• Set Aside: To Be Determined (TBD)

• Response Date: 18 March 2026

• Submission Method: Email responses to Lisa S. Armes (lisa.s.armes.civ@army.mil) and LaToya T. Whitsett (latoya.t.whitsett.civ@army.mil).

• Required Information: Interested parties must provide:

  1. Full company name
  2. Business size
  3. Applicable socio-economic status
  4. Points of Contact (name, position, office, phone, email)
  5. CAGE Code
  6. Unique Entity Identifier (UEI)

• This is an RFI only; it does not constitute a Request for Proposal (RFP) or a promise to issue one. Solicitations are not available at this time.

• No payment will be made for information submitted.

• Failure to respond does not preclude future participation.

• Potential offerors are responsible for monitoring SAM.GOV for future information.

Solicitation / RFP / RFQ

This document is a purchase description for the procurement of one (1) Lab Standard Microphone System, brand name or equivalent, for the U.S. Army TMDE Activity (USATA). The system is needed to replace three lost standard microphones (4180/4160 models) essential for the Acoustics Lab's reciprocity calibration. Failure to replace these standards could lead to a potential shutdown of the lab, impacting all accredited acoustic parameters.

The system shall include the following components or equivalent:

• One (1) 4180—PTO 1/2" Calibration Condenser Microphone, laboratory standard.
• One (1) ET-2014-W-002 Primary DPLA Microphone Calibration for 1/3 octave frequencies 10Hz to 25 kHz (for type 4180).
• One (1) 4160—PTO 1" Laboratory Standard Pressure Microphone, 200V Polarization.
• One (1) ET-2014-W-001 Primary DPLA Microphone Calibration for 1/3 octave frequencies 2Hz to 10kHz (for type 4160), calculated according to IEC 61094-2:2009/AMD1:2022.
• One (1) AO-0087-D-012 Cable, coax single screen, BNC (M) to BNC (M), 1.2m (4.0ft), max.+85°C (185°F).
• Shipping for two (2) items.

Shipping Address: U.S. Army TMDE Activity, Attn: Ricardo Gutierrez, Building 5435, Redstone Arsenal, AL 35898.

This appears to be a brand name justification or a direct purchase description, as it specifies particular model numbers and "or equivalent." Further details regarding submission instructions, evaluation criteria, contract type, period of performance, and deadlines are not provided in this document.
