Acoustic metamaterial structural geometry: BYDRecent Research Landscape

Uncontrolled broadband noise in high-airflow equipment leads to regulatory non-compliance and structural fatigue. These innovations engineer sub-wavelength geometric resonators to decouple sound attenuation from airflow resistance.

What technical problems is BYD addressing in Acoustic metamaterial structural geometry?

Excessive electric vehicle powertrain noise

(62)evidences

Unwanted noise and vibration generated by high-voltage battery components during operation. Mitigating these acoustic signatures improves passenger comfort and prevents structural fatigue in electric vehicles.

Inadequate acoustic integration space

(47)evidences

Limited internal volume in electronic devices and vehicles restricts sound quality and output power. Maximizing acoustic performance within constrained physical footprints provides a competitive advantage in compact hardware design.
