Story: Quiet fully automatic coffee machines
How can you influence the acoustics of a product retrospectively if essential components and parts in the design can no longer be changed? Novicos provided the answer for the fully automatic coffee machine division at Miele. Our team dismantled and analyzed the machine, carried out a transfer path analysis and calculated various possible solutions. Novicos then built a physical prototype to prove that the calculations were correct.

Sound characteristics
Optimization of the perceived sound quality
Not all sound is the same. We analyze the sound characteristics in order to better understand the acoustic properties of the sound sources and the effective environment. This knowledge enables tailor-made optimization measures for comfort and the human perception of sound. Depending on the application, we take the following aspects into account:
Sound source characteristics (frequency, amplitude, spectral composition)
Sound propagation characteristics (sound velocity, sound pressure, directional effect)
Room acoustic characteristics (room acoustics, reverberation time, sound absorption and reflection)
Total sound pressure level
Prediction of sound pressure as a basis for decision-making
The total sound pressure level is a value for evaluating and comparing operating noise levels. The higher the management level or the more inhomogeneous the team, the more relevant it becomes. Also for the
Total sound pressure level
Prediction of sound pressure as a basis for decision-making
The total sound pressure level is a value for evaluating and comparing operating noise levels. The higher the management level or the more inhomogeneous the team, the more relevant it becomes. This value is also relevant for the certification of products for compliance with legal guidelines and standards. We design measurements in such a way that the data collected provides the most helpful basis for decisions on how to proceed. We are happy to provide technical support for your project and deliver solution approaches and concepts to achieve your goals. On request, we can also take legal standards into account. For the pure DIN/ISO certification of end products without optimization requirements, we will be happy to refer you to a partner with a correspondingly standardized process.

Insulation materials
If the containment of a noise source is more economical or more sensible than its removal, we offer you comprehensive advice on the optimal use of insulation materials. Novicos advises you on material selection, design and the integration of insulation materials. We carry out acoustic measurements, calculate possible solutions and make predictions about the effectiveness of the insulation. Specifically, we support you as follows:
-
Sound transmission
Measurement of the transmission loss (TL) in the reverberation chamber with subsequent calculation of relevant values for sound transmission.
-
Absorption
Acoustic characterization by measuring the absorption in the impedance tube. Project example: Aerogels
-
Reflection
We determine the proportion of reflected sound from insulating materials by measuring it in an impedance tube or using a calculation model.

Multiphysical concepts and simulations
We record the influencing factors across disciplines and create multi-physical concepts. Our team consists of experts in acoustics, vibration, strength, flow, kinetics and electromagnetics. This enables us to penetrate even the most unusual applications. We work particularly frequently on NVH projects.
