摘要: An acoustic baffle for reducing noise of a centrifugal fan includes base mounting with outlet and projection extending from the length at back side curving away top surface base. The continuously tapers along least one an area proximate to apex. apex aligns tangency point, or trough midpoint outlet, when is installed in outlet. effects gradual variation radial tangential airflow blower reduce blade passage tone.
