Question
What is the effect of an incorrectly adjusted speech processor?
Answer Options
- A) Distorted speech
- B) Excess intermodulation products
- C) Excessive background noise
- D) All these choices are correct
Correct Answer: D
Explanation
A speech processor works by clipping or compressing the audio signal. If the processor’s gain or level is set too high, the audio signal is excessively clipped, leading to a host of problems.
The effects include distorted speech (a harsh, buzzy sound), the generation of excess intermodulation products (unwanted signals that cause ‘splatter’ into adjacent channels), and the unnecessary amplification of excessive background noise (which degrades readability). Because all of these undesirable outcomes are possible, an operator must carefully adjust the processor to use the minimum amount necessary to achieve improved readability.
