6 top-level parts · 188 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | DDS Tone Synthesizer | 2× | Stimulus + masking channel |
| 2 | Precision Step Attenuator | 2× | 1 dB steps, 120 dB range |
| 3 | Masking Noise Generator | 1× | NB / broadband noise |
| 4 | Transducer Output Amplifier | 2× | Low-distortion power stage matched to the impedance of each calibrated transducer output. |
| 5 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 6 | SMD Passive (R/C/L) | 180× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
