About the Course
is a comprehensive acoustic measurement platform, which provides the
user with a wide range of field as well as lab measurement,
post-processing and assessement possibilities.
This online course covers the measurement platform and addresses the theoretical background that the user needs to use the tool.
Upon completion of the course, the students will1. get acquainted with the theoretical background in acoustics and digital signal processing for using EASERA,
For Whom Is the Course?
The course is designed for those, who are involved in setting up, testing, commissioning and measuring room acoustics, sound reinforcement, voice alarm systems and components.
Previous knowledge and experience with acoustical measurements would be helpful but are not prerequisites for the course.
Students, however, are assumed to have a reasonable level of engineering general knowledge and to understand the basic definitions and terminology.
Direct E-Mail Support
Each course student shall have access to direct and personal e-mail support for the course curriculum for ninety days from the day of enrollment or releasing course material online, whichever is later.
During this period, the student can send his/her questions to the instructor, and shall receive an answer from the instructor within 48 hours at latest.
The e-mail support can be extended to one year against extra charge.
Testing and Certification
After each lecture, students shall have the chance to take a number of quizzes to test their progress with the course topics.
At the end of the course, there shall be a final set of quizzes to test the students' knowledge of the entire course and how far the met the objectives.
Certificates for this course are issued by sistrum.eu in cooperation with AFMG® Technologies GmbH. A certificate of successful completion shall be issued to the students, whose overall score based on all quizzes in the course including the final set is 75% or better.
