Question 1: What is the role of "acoustic sealing" in reducing road noise in automotive design?

Which action should you take?

Choose only one option

To amplify engine sound for performance cars

To seal gaps in the body and prevent noise from entering the cabin

To allow vibration transmission through the body

To improve the airflow in the engine compartment

Question 2: In sound quality analysis for automotive applications, what is the purpose of using a binaural microphone setup?

Which action should you take?

Choose only one option

To simulate engine sounds during acceleration

To isolate specific frequencies in the sound spectrum

To measure the sound pressure levels in the cabin

To capture sound from a human-like perspective for realistic sound analysis

Question 3: What is the role of critical band analysis in automotive sound quality analysis?

Which action should you take?

Choose only one option

It measures the resonance frequencies of the vehicle's chassis

It helps model how the human ear perceives sound in different frequency bands, influencing how noise is experienced in the cabin

It determines the frequency range for the engine's operating speed

It calculates the noise reduction achieved by soundproofing materials

Question 4: What is the main purpose of conducting a sweep sine vibration test on automotive components?

Which action should you take?

Choose only one option

To determine the frequency response and identify resonance frequencies

To test the component's material strength

To simulate real-world driving conditions

To measure the total power output of the component

Question 5: When calibrating NVH test equipment, why is it important to use traceable standards and certified reference equipment?

Which action should you take?

Choose only one option

To ensure that measurements are accurate and comparable to global standards

To ensure that the system operates in a closed-loop mode

To increase the speed of the testing process

To reduce the cost of testing by using uncalibrated equipment

Question 6: What is the effect of improper calibration of a vibration transducer on NVH test results?

Which action should you take?

Choose only one option

It may lead to inaccurate measurements, affecting data analysis and decision-making

It will cause minor inaccuracies that are easily correctable

It will not affect the overall results if the device is working

It will primarily impact high-frequency data only
