Question 1: When conducting vibration testing on automotive suspension components, what is typically measured?

Which action should you take?

Choose only one option

The pressure of fluid in the suspension system

The frequency and amplitude of vibrations at different points of the suspension system

The displacement of the suspension components

The heat generated by the suspension components during operation

Question 2: How do you optimize the design of a vehicle's door seal system to minimize wind noise?

Which action should you take?

Choose only one option

By improving the seal material, shape, and compression characteristics to prevent air leakage

By ignoring the sealing characteristics and focusing on aesthetics

By increasing the weight of the door

By using only rigid materials for better sealing

Question 3: What is the significance of the loudness level in automotive sound quality analysis?

Which action should you take?

Choose only one option

Loudness is used to calculate the fuel efficiency of the vehicle

Loudness reflects how the human ear perceives the intensity of sound, influencing the perceived comfort of the vehicle's cabin

Loudness measures only the frequency distribution of sound

Loudness quantifies only the noise levels from the exhaust

Question 4: In sound quality analysis, what does the term "flutter" refer to, and what component is commonly associated with it in automotive systems?

Which action should you take?

Choose only one option

A low-frequency rumble; associated with the exhaust system

A type of high-frequency noise; associated with the transmission

A phenomenon of rapid oscillations; associated with door panels or interior trim

A mid-frequency hum; associated with the HVAC system

Question 5: Which standard is commonly referenced for the calibration of sound level meters used in automotive NVH testing?

Which action should you take?

Choose only one option

ISO 9001

SAE J1455

ANSI S1.4

IEC 61672

Question 6: In automotive suspension vibration analysis, what is the main purpose of conducting a shaker table test?

Which action should you take?

Choose only one option

To evaluate the thermal properties of suspension components

To simulate road conditions and measure suspension response

To assess the aerodynamic performance of the suspension

To test the electrical components of the suspension system
