pubIlc BUILDINGS.

To the Honorable the Common Council:
Gentlemen-Your Committee on Public
Buildings TO whom was referred the com
munication from the III. w. Johns-Man-
Vile Co. submitted at the request OF the
City Clerk in relation TO the accoustical
conditions OF the Council chamber, re-
srectfully report that we have had the
same under consideration and beg leave
to state that after an extensive invest-
CATION made by said firm, they submit
a proposal for the correction OF the acous-
tical properties OF the chamber, In con-
nection with which they state that the
trouble experienced I'm this Council cham
ber IL not uncommon and characteristic
OF rooms OF this type; that the compare
tive lofty ceiling and plastered walls are
firm, hard and excellent refiectors and
all the sound striking them travels with
but slight diminution through many re-
Elections before returning TO the auditors;
that this return Is so long after the
sound which has come directly, as to pro-
duce confusion instead OF the desired re-
infoI cement; that to correct the difiicul-
ties OF such problem as this Is by alb
sorbing the sound which produces the dis
turbances at surfaces from which IL ls
DETECTED the greatest number OF times:
that they have carefully traced these
sound rays and they propose TO treat
certain portions Of the side and north
walls and ceiling panels with sound-ab-
sorbing felts. over which will be applied
durable fabric decorated TO harmonic
with the rest OF the chamber: that their
proposal includes the re-decroating OF
these surfaces covered by their material
and thoroughly cleaning and re-touching
all the surfaces I'm the room with the
exception OF the wood work, which will
obvtate any possibility OF their work hav-
ing distinctly new appearance and will.
az the same time. brighten up the entire
chamber: that the cost OF correcting the
acoustical properties as estimated by
said firm will be s2.345.O0. and your Com
mittee believe that something should oe
done to remedy existing conditions. but
lrasmuch as there are no available funds
from which this sum can at present be
appropriated we recommend that the
City Controller be directed TO include
said sum In his estimate for the ensuing
fiscal year. in order that an appropriation
may be obtained therefore through the
proper channels provided by law.
Respectfully submitted.
