Dear C. ‘5

I have a pamphlet put out by the Acousti-Celotex pecple
on sound conditioning for educational buildings. They are
now using this material for gymmasium ceilings, and it.
seems to me it would be well to consider the use of celotex
for our building when the gymmasium is re-wired.

Sincerely yours,

In penetrating and traveling through this maze, the
sound wave encounters just enough resistance to create
friction which transforms the acoustic energy into heat.

Practically, the sound is “soaked up” by the material
rather than reflected back into the room.

l How does Sound Conditioning “stop” noise?

Sound Conditioning in itself does not stop noise;
a cough, a typewriter, a dropped tray, a bookkeeping
machine, a ringing telephone bell, a punch press, a band
saw or any other noise source generates as much acoustic
energy in one location as another.

The loudness is lessened in a sound conditioned room
because the original sound dies out faster. It is not ampli-
fied by repeated reflections from ceiling to floor and wall
to wall as it is in an average room.

Sound is reflected from a hard surface just as light is
reflected by a mirror. In the average room with hard
plaster walls and ceilings, the sound traveling at an
approximate speed of 1120 feet per second, will bounce
around the room in all directions many times before the
energy it contains is dissipated, or absorbed.

The acoustical material used for sound conditioning

absorbs far more of this energy than do ordinary ma-
terials, thereby hastening the silencing of the sound.

Ib How is “Adequate Absorption” determined
for a room?
If your car travels 14 miles on one gallon of gasoline and
you now have five gallons in the tank, with a journey of
182 miles before you—you can easily calculate that eight
gallons more will be required to make the trip.
Likewise, the Sound Conditioning Engineer knows the
present absorption capacities of the materials and fur-
nishings in a room, and how far present average noise
levels can be profitably lowered by additional absorption.
From this he can easily calculate how much additional
absorption is required to bring a satisfactory result.

1/7 Is it possible to calculate the length of time
sound will remain audible in an auditorium
after the source has ceased?

Yes, the period of reverberation can be mathematically
determined by means of the Sabine Formula:

T= 05
a
T equals reverberation time measured in seconds.
V equals volume of room expressed in cubic feet.
a equals all existing sound absorbing units.

| If the period of reverberation is too long,
what are the effects?

If a single sound remains audible too long after it has

been stopped at its source, it combines with the following

sound, or sounds, from the same source, creating a com-

plex mixture of the several sounds. When this effect is

pronounced, the ear cannot distinguish clearly between
the individual sounds. For instance, a speaker’s words
will telescope with those previously spoken making entire
prases “blurred,” “fuzzy” and unintelligible.

Music is scrambled in the same way by the “echoes”
in an excessively reverberant room. In rehearsals, the
conductor or instructor finds difficulty in locating and
correcting mistakes.

| Is Reverberation the sole cause of poor
acoustics ?

In the majority of instances it is. With few exceptions,
removal of excessive reverberation will create good
hearing conditions.

In occasional cases the shape of a room or unwisely
placed curved surfaces which focus sound at specific
points will interfere with satisfactory sound distribution.

2 Is all Reverberation undesirable?

No. A certain amount is essential if speaking and
music are to have a pleasing “live” quality.

2 Can Loud Speakers overcome faulty hear-
ing conditions in an auditorium?

Asa general rule, no. If reverberation is excessive, speech
can not be understood no matter how much it is ampli-
fied. The function of loud speakers is to increase the
power of the natural voice, when necessary.

2 Is there a proper reverberation time for
auditoriums of different sizes and capac-

ities, and how is it determined?

Yes. This is known as the Optimum Reverberation time.

Through painstaking experiment and years of experi-
ence and observation, the most satisfactory length of
time, in seconds, for sounds to die out in auditoriums of
various sizes has become known. This is a matter of record
and is used as a base in correcting auditorium acoustics.

2 Does Acousti-Celotex Sound Conditioning

cost more to install in existing school build-
ings than in new ones?
No, in most installations the cost is the same.

2 Does installation of Acousti-Celotex require
structural changes in existing buildings?
No, absolutely no structural changes are required.

2 Who applies Acousti-Celotex Sound Con-
ditioning?

Only approved distributors who have organizations
trained for accurate engineering and expert application.
These distributors are selected by The Celotex Corpora-
tion and given thorough training in Acousti engineering
and Sound Conditioning practices. See back page of
Celotex Sound Conditioning Service.
  

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.”

H. D. E_pripce, Superintendent,
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-

head What Some Schools Think of
Acousti-Gelotex Sound Conditioning

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.”

ReeEDE Gray, Superintendent,
The Public Schools,
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.”

Louts& SCHUEFFNER, Music Supervisor,
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.

SELECTING THE PROPER MATERIALS

The sound conditioning of building interiors usu-
ally requires the introduction of sound-absorbing
materials for comfortable and efficient use. Products
designed specifically for this purpose are commonly
known as acoustical products.

Celotex acoustical products include Acousti-
Celotex cane and mineral tiles (top two pictures)
and Muffletone standard and fissured tiles (two
lower pictures). Both are made in different thick-
nesses, thus providing a range of sound absorption
from which proper selection can be made in each
case.

Acousti-Celotex (Cane)

 

Muffletone (Standard )

 

Each area to be sound conditioned must be accu-
rately analyzed and engineered so that the right
material may be specified to produce the results
desired.

Which material to use, how and where to install
it for best results, the mechanics of efficient, eco-
nomical erection—these important questions may
be safely left in the hands of the local Celotex Sound
Conditioning distributor. Part of the world’s most
widely experienced organization in this field, he can
be depended upon for competent, efficient service.

Dear Mr, Bayless —

' Our old diving board is worn out and our new diving
board needs things to be done that Mr. Davidson cannot do, due
to the fact that he does not have the proper tools.

As I understand it, there must be a cut into the
concrete with the proper installation, Will you kindly send
one of your men over,and we will have Mr. Reginald Strait
go over the project with him so that he can give us an estimate
as to the cost of installation, We will then issue a request
and a requisition for this work.

Sincerely yours,

Mr. C. G. Bayles, Supt.,

Dear Mr. Bayless

I em confirming my phone conversation regarding the leaks in my office,
which is in the southwest corner of Robinson Gyrmasium. The water fairly
pours dow from the conjoined margin of the deiling dnd the west wall. I
immediately supposed there was a window open in the Naval officers quarters
directly above my office. I called Chief Gathings and he hurried over, but
the room above was as dry as a bone. |

Then I called you and you asked me to get the janitor. I got Ry Jackson |
and me made a thorough inspection of the K Room windows, and that room is
utterly dry. Then we inspected the outside. ‘The only way it appears to me
that it would come in is through the ledge above the windows in the officers
quarters at the soutiwest corner of the tuilding. Rain is admitted from
above, not the eaves, but the ledge above the windows. I would say, conser~ —
vatively, two gallons of water came in my office. I have ten towels and
they are sepping wet. <5 ee

The water strikes the baseboard as it drips from the molding on the wall
which is set in one foot from the window. It also splashes against the
radiator which is a 6~inch inset from the window ledge, and then it splashes
ever on my desk and spoils a let of correspondence and books on my desk, which
is two feet from the radiator.

The south windows of my reom leak enough to admit water, but the glass air
ventilatoxs in a way protect it from coming in on the sill. But an equally
bad situation is on the south windows in the long room just to my left.
These two south windows lead water from the top, which convinces me that the
seme situation exists in those south windows that exists in the windows above
the officers quarters. The used towels which the men in physical education
and officers use are piled high on a locker, We use those te sop up the
water during and after a rain. .

Also, the windows on the west side in ow front office, where Henry Shenk,
Reg Strait and Ray Kanehl are, leak from the bottem enough so that it is
necessary to put three or four towels on the ledges or else the water will
stand there in pools. Even though the windows are closed tight and locked,

. the water still runs in, in great quantities. — si

Dear Mr. Bayles:

_ Your. men have done a swell job on the ititeitialnig ot the
steps at the west entrance to the gymnasium, but there are two
steps and the riser or platform yet to be chiseled. When this
job is finished it will be a great improvement in the safe of
the steps.

One other suggestion: There are no electrical outlets in
rooms 203 and 206 in the gymmasium, and many times we desire to
set up a projector for pictures in these classrooms. It is then:
necessary to run an extension cord to the K-Room or some other
place to plug it,in. We would greatly appreciate it if you can
have outlets put in these two classrooms.

‘Dear Mr. Bayles:

The front steps to the west entrance of Robinson Gymasium have
become so worn by the footsteps of time that whenever a rain or snow
comes with a freeze it makes these steps treacherous and very, very
dangerous. While I ask the janitor to use sand at every opportunity,
yet there are times that this is not possible, and I fear for the
severe injury that may come to some of the people using them in those
dangerous times. -

The water does not drain off due to the depression wear. There-
fore, I believe the only thing that oan help these steps would be a
chipping or roughing up of the surface se that it would render them
less hazardous.

In descending these steps when any ice is on them it is impossible
for anyone to get a foothold, and sinse the steps are wide and there is
no railing that a person could hold on to, the hazard is double. 2

I have been expecting to speak to you about this for over 4 year,
sc I know of no better time than now to urge your inspeotion of this
hagard.
