Supply of Hearing, Screening Device (Automated Auditory Brainstem Response, Otoacoustic Emission Test and Tympanometry)
AI Summary
The University of the Philippines – Manila is issuing a tender for the supply of a comprehensive hearing screening system to be installed at the Newborn Hearing Screening Reference Center, National Institutes of Health. The contract requests a single, integrated device that will replace multiple standalone instruments currently used for newborn auditory screening, thereby enhancing laboratory workflow and ensuring consistent, regulatory‑aligned results. The system is expected to deliver all required assessments within a single piece of equipment, facilitating efficient use of space and resources in a busy clinical setting.
This multi‑function device must provide distortional product otoacoustic emissions (DPOAE), transient evoked otoacoustic emissions (TEOAE), automated auditory brainstem response (AABR), and tympanometry. Specifications include dual‑tone DPOAE stimuli at 65/55 or 60/50 dB SPL across various F2 frequency ranges, 50–80 click per second TEOAE at 70–84 dB SPL with a signal‑to‑noise ratio of at least 3–6 dB, and AABR clicks of 0.1 ms at 35 dB nHL with a sweep rate of 32–62 per second. Tympanometry must support a range of probe tones (226 Hz to 8 kHz), pressures from –600 to +300 daPa, and compliance measurements up to 8 mL at 226 Hz. The equipment must be NHSRC certified, compatible with ENNHSR integration, and accompany a two‑year warranty and one‑year free calibration service.
The device must comply with NHSRC certification, deliver DPOAE and TEOAE measurements according to UK guidelines, support AABR with stimuli of 0.1 ms click at 35 dB nHL, and perform tympanometry across 226–8000 Hz with a pressure range of –600 to +300 daPa.
