Smartphone-based active sound design for enhancing engine sound of vehicles
This study explores the implementation and effectiveness of smartphone-based active sound design (ASD) in enhancing the engine sound characteristics of vehicles. Traditionally confined to high-end automotive applications, ASD technology utilizes built-in audio systems to improve the auditory experience inside vehicles. This research extends the utility of ASD to standard production vehicles through integration with smartphones, leveraging Bluetooth connectivity for CAN-BUS data, such as engine speed and accelerator pedal sensitivity. The smartphone-based ASD system was implemented in a 6-cylinder gasoline engine sport sedan. Through driving tests, the synthesized engine sound was evaluated alongside real engine sound and artificial sound output, comparing both the smartphone-based ASD system and the conventional car audio-based system. Experimental results indicate that the smartphone-based ASD effectively emulates the sound enhancement capabilities of traditional systems, with minimal discrepancies in performance. This study confirms the potential of integrating ASD technology with consumer smartphones, offering a scalable and accessible approach to enhancing vehicle engine sounds. This expands the application scope of ASD and fosters innovation in automotive sound design.
期刊介绍:
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
