Accordingly noise levels generally within these parameters would <br />be in compliance with the more general standard of 33- <br />8.005(10)(a)6. <br />The ACA recommended standard was proffered as a standard at the <br />time the acoustics requirement for local Florida detention <br />facilities was enacted. In deference to the Florida Sheriffs <br />Association this standard was not expressly adopted so as to. <br />enable local detention facilities some leeway in construction and <br />to avoid controversy arising from an unduly rigid standard. <br />In the event the existing regulation is deemed unacceptable, I <br />suggest that the ACA standard be promulgated. <br />Please advise if other details are needed. <br />The Administrator informed the Board that while we do not <br />have empirically derived evidence as to the acoustics level in <br />the jail, there were some readings taken by a private firm that <br />came in to do an inspection, and the person who took the readings <br />seems to recall that the ambiant level daytime was 85 dba. <br />Since, as noted in his memo, every one decibel increase is an <br />increase in sound power of 26%, an increase of ten decibels is <br />fairly substantial. <br />Commissioner Bird wondered how much the decibel level will <br />vary when we relieve the overcrowding situation and get that jail <br />down to its normal population. <br />Administrator Balczun believed there is a tremendous <br />difference between sound volume and sound power. He noted that <br />while the hexagonal design of the pods is very efficient in terms <br />of jail design, it is very inefficient in terms of sound, and <br />sound bounces all over the place. <br />Chairman Scurlock personally felt the architects had a <br />significant responsibility in designing this facility. Although <br />the D.O.C. did not have specific criteria at the time, there is a <br />great deal of literature available on sound levels, and all the <br />literature he has read on this subject would seem to indicate <br />that an architect should have had available the knowledge that 70 <br />and 40 are reasonable sound levels and they should have designed <br />for that criteria. While he realized we will have to make <br />37 <br />MAY 1 0 '1988 <br />BOOK 72 PAGE 317 <br />
