NEMPEE
ACOUSTICS SOFTWARE For
Architectural Acoustics
This
is a powerful Software tool for Acoustics
Engineers & Architects.
Based on Mathematical calculations, it
determines the acoustical parameters of a room,
such as the reverberation time.

Screen
for entering the
information related with the Project and
the Client.
You
can select your Measurement System Either
Meter or Feet
|
|
|
Select
the Application type.
Enter
the Volume.
Enter
the Humidity.
Select
the Surfaces & Enter the Areas of the
surfaces present, like floor, wall and
ceiling.
The
desired reverberation time & average
Absorption Coefficient will be calculated
for reference and as a target.
|
 |
|
Select
Absorption materials
from The database, and apply to the
surfaces.
You
can Add more Materials to this database.
|
 |
|
Enter
Areas for Applied Materials surfaces.
During
the design process, the resulting
reverberation figures & curves are
shown continuously, thereby providing the
designer with a highly convenient
feedback.

At
the end, this will give a very detailed report of
all the materials applied on various
surfaces with their areas & absorption
coefficients.
Eyring's
Reverberation Formula
This
Formula is applicable to all rooms where diffused
conditions of sound exist.
This formula is more universal in application than
any other formula.
Effect Of Shape Of the Room
The
Reverberation Formulae are based on statistical
calculations, using the total room volume and the
total absorption present, assuming a diffuse sound
field. The
reverberation time depends on the mean free path.
The formula we used considers the room
shape as rectangular.
This mean free path varies with different
shapes. But
in practice this formula has proven to be a good
approximation of reality. Maximum error of 8 to 10
% may result with very odd shapes.
Calculate
the required quantity of absorption material with
the help of NEMPEE Acoustics Software.
The
location of the absorbent material to be worked
out according to rules accepted by experience.
Reverberation
measurements are taken after the room is completed
& modifications, if necessary, should be done
to obtain the desired reverberation.
We
are not responsible for any error in data
parameters or the final acoustics performance of
the room.
You
Must have "MS Data Acc Component 2"
installed (mdac_typ)
it
comes with IE 5 & +
