Set for this particular application, including these items:

a) Sensor:

An acoustic sensor (microphone) of high sensitivity.

b) Elements:

3 Acoustic sources (trumpets):
Two of them are of low frequency 450Hz, 90dB and the third one of high frequency 4500Hz and 90dB, with
supply of 12V. AC.
Anacoic camera with walls covered with polyurethane of high intensity. It will allow you to isolate your experiments
from external noises, allowing you to obtain the waves produced by the sound source supplied.
Microphone of high sensitivity.
Flat wall covered with high density polyurethane and orifice of 10 mm.
Inclined wall and 45º with possibility of being recovered with foam of high density.
Buzzer.
The teacher can use any element suitable for ACOUSTICS study, so the UNIT IS OPEN and can do MANY
OTHER EXPERIMENTS.

c) Computer Control Software:

Computer Control+Data Acquisition+Data Management Software for Acoustics Study application.
Compatible with actual Windows operating systems. Graphic and intuitive simulation of the process in screen.
Compatible with the industry standards.
Registration and visualization of all process variables in an automatic and simultaneously way.
Flexible and open software, developed with actual windows graphic systems, acting simultaneously on all process
parameters.
Management, processing, comparison and storage of data.
Sampling velocity up to 250,000 data per second.
Student calibration system for all sensors involved in the process.
It allows the registration of the alarms state and the graphic representation in real time. Comparative analysis of the
obtained data, after the process and modification of the conditions during the process.
Open software, allowing to the teacher to modify texts, instructions. Teacher’s and student’s passwords to facilitate
the teacher’s control on the student, and allowing the access at different work levels.
This unit allows that the 30 students of the classroom can visualize simultaneously all results and
manipulation of the unit, during the process, by using a projector.
