Summary
Automobile auditory signals should be calm and dull, avoiding sharp, high-frequency sounds. This design benefits all users, including the elderly, ensuring signals are easily heard over interior noise.
Area of Science:
- Human-Computer Interaction
- Acoustic Engineering
- Automotive Design
Background:
- Auditory signals in vehicles are crucial for alerts and information.
- Current automotive sounds vary widely in effectiveness and user perception.
- Optimizing auditory signals is essential for driver safety and comfort.
Purpose of the Study:
- To evaluate user impressions of various automotive auditory signals.
- To determine desirable acoustic characteristics for vehicle sound design.
- To ensure auditory signals are perceptible and not masked by interior noise.
Main Methods:
- Semantic differential method used for comprehensive evaluation of auditory signals.
- Analysis of frequency spectrum of interior vehicle noise.
- Comparison of signal characteristics with noise profiles.
Main Results:
- Sharp sounds with high-frequency components are unsuitable for automotive use.
- Calm, dull sounds with longer intermittent OFF times are preferred.
- Suitable sounds are less likely to be masked by the vehicle's interior noise.
Conclusions:
- Automotive auditory signals should prioritize "dull" and "calm" acoustic properties.
- Signal design should consider age-related hearing decline, particularly in high frequencies.
- Optimized auditory signals contribute to universal design principles in vehicles.
