A fast and inexpensive method for the behavioral determination of hearing parameters like hearing thresholds, hearing impairments or phantom perceptions (subjective tinnitus) is described. It uses pre-pulse inhibition of the acoustic startle response and can be easily implemented in a personal computer using a programmable AD/DA-converter and a piezo sensor.

FAQs
Angular adjustment sets the prism’s incidence angle, which controls how incoming light interacts with its surfaces through refraction, reflection, or beam deviation. Translation positions the prism within the intended optical path. Using both adjustments allows engineers to place the prism correctly and establish the light direction required for a measurement or operating configuration.
The holder must provide enough constraint to keep the prism stable while leaving the relevant surfaces available for light interaction. Excessive obstruction could interfere with the intended optical path, whereas insufficient constraint may allow positional changes. This balance supports controlled optical behavior and helps preserve alignment during testing or operation.
Poor stabilization can introduce vibration, beam displacement, and alignment errors. These effects change the prism’s relationship to the optical path, making the resulting light behavior less consistent. In engineering measurements, controlling mechanical stability and alignment is therefore important for obtaining repeatable prism positioning and dependable optical results.
Begin by mounting the prism so the holder constrains it without obstructing the relevant surfaces. Next, position the assembly in the intended optical path, then adjust angular position and translation to establish the required incidence angle and beam direction. The final arrangement should minimize instability and preserve the alignment needed for operation or measurement.
This setup supports optical testing, spectroscopy, imaging, and instrumentation. In each case, the holder provides a controlled way to position the prism while the optical path is established. Its value is greatest when experiments or instruments require the prism to remain consistently located so that light interacts with it in a predictable configuration.
A carefully aligned arrangement provides repeatable prism positioning and more reliable control of light interaction with the prism. Depending on the application, this supports the intended refraction, reflection, or beam deviation during measurement or operation. Reducing vibration, beam displacement, and alignment errors also improves confidence in optical testing and instrument performance.
