A local bar in town has submitted an application to amend its liquor license to permit live outdoor (amplified) music in an existing outdoor patio area (approximately 1,800 square feet) which is surrounded by a 6-foot wood privacy fence. The City Council asked that the Community Development Department explore sound deadening materials to absorb the sound within the fenced area. I'm not a sound engineer, but my guess is, unless you completely enclose the area, sound will escape through the area not enclosed by fencing. Adding sound dampening material to the fence, in my opinion, won't substantially absorb the sound.
Have any of you dealt with bars that wanted outdoor amplified music and, if so, what did you do to help mitigate the noise level? We could look at limiting dB's to no more than the ambiant noise level, or to prohibit amplified music all together, however, I think the Council is looking for ways to absorb the sound within the fenced area.
Thank you in advance.
