Active noise control mechanism for the low-frequency sound field of a cylindrical shell

Key Points

• Active noise control successfully reduces low-frequency sound levels in cylindrical shells, improving acoustic comfort.
• Significant reduction of sound pressure levels was observed during testing at various frequencies and sound pressure levels.
• Analysis centered on the intervention mechanism of active noise control in cylindrical structures and its effectiveness.
• Techniques may enhance sound insulation measures in industrial and architectural designs, further research could expand its applications.
