Question

Read this sentence from chapter 8.“As I’m certain you are aware, the problem in the past with this new technology in automotive sound has been road vibrations interfering with an accurate dispersal of the phonic interpretations.” What does the word “accurate” mean as used in this sentence?

Answer 1

The word 'accurate' in the context of the sentence refers to the correctness or precision of the automotive sound system's sound dispersal, unaffected by road vibrations.

Step-by-step explanation:

The word “accurate” as used in the sentence means correct or precise in this context, referring to the automotive sound system's ability to produce sound without distortions caused by road vibrations. In the field of mechanical engineering, accuracy is crucial when diagnosing problems with automobile parts using sound analysis.

Engineers might use Fourier analysis to detect resonating frequencies that indicate an issue with a component of a vehicle. These resonances can cause significant noise and potentially lead to the premature failure of the part. Alterations to the part's material or dimensions may be required to fix the issue and ensure an accurate functioning of the vehicle's system.

Answer 2

As far as I know vehicle traveling vibration is random. It means that there is no one exact frequency. Of course if there are not regular cavities in the road. The dominating frequency range on the body (sprung mass) is for passengers cars approx 1-2 Hz. This is because of suspension natural frequency. This range is well tolerated by the human body. That is why this range is chosen. But I am not the specialist so anyone can correct me at will.
