Sound Conditioning with Acousti-Celotex is not an
experiment . . . It is today serving in hundreds of
schools, colleges and universities in all parts of the
nation. Read what some of them have to say. . .

“T am writing to congratulate you on the excellent job
of sound conditioning the new University High School
... The contrast between this school and the other schools
not so treated is very evident and is remarked upon by
all visitors. The noise-subduing effect of the treatment
in corridors and halls is most evident and we are highly
pleased with the work,” writes B. F. Pittenger, Dean of
the School of Education, The University of Texas at
Austin.

Brother Anthony, Superior of Morris Institute at
Searcy, Arkansas, comments, “We derive quite a little
amusement from visitors and inspectors by whom we are
frequently asked, ‘why we do not allow the boys to be as
noisy in the gym as in the adjoining playhalls.’ Although
they saw the boys run and romp as only boys can do with
mouths wide open, the visitors felt that restrictions had
been imposed until we explained to them the effect of
Acousti-Celotex on the ceiling.”

“One of the most appreciated features of our new
Greeley Junior High School building is the Acousti-
Celotex sound conditioning. Pupils, teachers, and school
patrons are universal in their commendation.

“Having moved our general school offices from the
High School buildings which is not so treated to this
building, I can assure you that the difference is very
noticeable. Hundreds of students passing in hallways and
coming out of classrooms will cause a certain amount of
noise. In this building that noise is cut to a minimum.
This treatment, plus the large amount of natural lighting
which we have, has made our building one of the most
modern in this part of the country.”

City Schools, Greeley, Colorado

“Three years ago we placed pre-painted Acousti-
Celotex on the ceiling of the Lincoln School auditorium.
This treatment changed the room from a ‘rainbarrel’ to
an auditorium with perfect acoustics. Two years ago we
treated the ceilings of all corridors, music rooms, and
office quarters in the Lincoln Building. Our new $300,000
addition has complete Acousti-Celotex Sound Condition-

ing. The latter includes all classrooms, corridors, gym-
nasium-auditorium, music rooms, etc. The band room is
perfect. It confines all sound. In general, may I say that
it prevents teachers’ and pupils’ nerves from getting on
edge. It is conducive to quiet concentration.”

Redwood Falls, Minnesota

“In your recent letter you asked me for a recommen-
dation for the Acousti-Celotex you placed on the audi-
torium ceiling.

“I gave an operetta last fall, before you worked on
the auditorium; although the students spoke distinctly
it was quite impossible to hear. I found that choruses
and glee clubs flatted a half pitch due to the echo. I have
had no trouble since the auditorium has been treated.
Children, adults, and choruses can all be heard without
any straining on the part of the listener.

“Inasmuch as all my work is practically in the audi-
torium, I find that I no longer have to work and be on a

‘nervous tension.”

Kouts High School, Kouts, Indiana

From Charles A. Smith, Kansas City, Architect, “For
a number of years I have been using acoustical treatment
in the Auditoriums, Music and Expression rooms, Gym-
nasiums and Swimming Pool rooms of all school build-
ings, wherever the funds available would allow its use.
The beneficial results more than justify the cost.”

“I have used Acousti-Celotex treatment in twenty-five
school buildings in Kansas City, Missouri, and in many
other buildings in the surrounding territory, with uni-
formly satisfactory results.

“The Irvington School has Acousti-Celotex ceilings
throughout and the difference in quietness between that
building and all other school buildings of the city, is
amazing. There is a peace and a relaxed atmosphere
which not only simplifies the task of administration, but
also improves the disposition and temperament of teach-
ers and pupils. It is one of the greatest agencies for men-
tal hygiene that can be introduced into the school house.”

H. M. Barr, Director Research Dept.,
Portland, Oregon, Public Schools

“Iowa State College has installed a considerable
amount of acoustical treatment in the past few years and
among the rooms which have been treated are lecture
and classrooms, accounting offices, small radio broad-
casting booth, playing room for the carillon, and a dor-
mitory recreation room. Persons who have occasion to
use these rooms are apparently very well pleased with
the results which have been obtained.
