Abstract
The design of PC programmable digital hearing-testing device is described in this paper targeting the testing of hearing impairedness in a laboratory environment. It is used to measure the response of each ear at different frequencies and at different sound pressure level (SPL). The device input is the serial 12-bit data and 7-bit control signal from USB connection while the output signal is sound waves with frequency range from 20 Hz to 20 KHz. This device is designed and simulated in 0.18 mum CMOS technology. It is composed of digital components except for the active filter. The device is designed as a single chip to fit on a 32 Omega headphones and powered by 1.3 V supply. The device is designed without using any ADC and DAC converters. Improved designs of 12-bit counter, clock generator and control are proposed. PWM generator is designed using digital components only to provide more accuracy and reliability. A second order, Butter-worth active low-pass filter is used as demodulator. The SPL output of the device is PC controllable through the USB connection

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
