Since the start of the CORONA crisis, air purification devices have been used in numerous classrooms, offices, homes and medical practices. They make an essential contribution to combating the pandemic. However, due to the high flow rate in compact systems, air purifiers can also generate unpleasantly high noise levels. We want to tackle this challenge together with you as a manufacturer of air purification systems.
We can assist you with your measurement or development project, starting with project development, through metrological analyses and model calculations, right up to the construction of low-noise air purification devices.
As an institute for building physics, we have decades of experience in noise control. From anechoic to reverberation chambers, we have a wide range of highly-specific acoustic test equipment at our disposal in our technical center. Coupled with our extensive measurement and analysis procedures, we can deal with almost any acoustic issue relating to noise reduction.
At Fraunhofer IBP, we can also give you competent advice and support in optimizing the purification performance of your equipment. In addition, for further topics such as structural strength or CE conformity, we can draw on a pool of expertise from more than 70 other Fraunhofer institutes and put you in touch with the right Fraunhofer-Gesellschaft experts.
We carry out sound power measurements according to ISO 3741 or ISO 3743. Sound power and the associated volume flow allow a planner to check whether your air purification system meets requirements and whether the resulting sound pressure level in the room complies with the recommendation in VDI 2081, for example.
Of course, we also assist you in more far-reaching project-based developments to reduce noise. We would be happy to send you a proposal in the form of a project outline, covering anything from initial metrological analyses of the existing system to the development of a low-noise ventilation unit. As a rule, these cases call for sophisticated metrological analyses which go beyond simple sound power measurements. We use iterative measuring and analysis methods to identify the problem and to devise solutions for reducing noise levels. You then produce and integrate the developed measures or modify the air purification system yourself or in close cooperation with an external company. Subsequently, the acoustically adapted air purifier is validated by measurements in our testing facility. The results are presented to you in our institute by means of a demonstration in our test rooms. A formal report and a summary of the development work and results conclude the research and development project.
Are you interested in a cooperation? We are looking forward to hearing from you!
