Good Chamber Type Spark Arresting–
Expected Attenuation is 17 to 20 dBA
Use a model MSA1 in residential and light industrial
areas for spark arresting capability where
background noise is relatively high and constant and
the need for higher degrees of silencing is minimal.
Example: In residential neighborhoods having high
traffic or light industry with relatively constant
background noise. Residents in these areas are
typically accustomed to the noise or make some
efforts to shield themselves from the ever present
background noise . Use of an MSA1 can keep engine
exhaust noise within existing noise levels. |
