Next to styling, sound design and noise reduction are taking an increasingly important role in the development of products. Components like fans often produce annoying noise, also - according to a study of the WHO (World Health Organization) - the consequence of prolonged exposure to sound pollution is potentially harmful to humans. 

 

GIANT

GIANT has asked Sorama to support their R&D team with respect to improving the sound design of silent ebikes. The market growth is amazing and a growing number of people are using ebikes for travelling to work. In addition, ebikes are increasingly being used for making biking trips in rural areas or in the countryside. In every circumstance it is very important that bikers do not get distracted or annoyed by a noisy ebike.

Sorama performed measurements at GIANT E-bikes in Lelystad, the Netherlands and provided a detailed analysis of the data measurement with both the Sorama CAM1K and the CAM64. Consequently, during an image and video presentation a number of clear cut recommendations were offered on how to improve the dynamic behavior of GIANT ebikes regarding vibrations and sound.

After the recommendations were implemented, the sound behavior of GIANT E-bikes was drastically improved. “This has already increased our customers’ satisfaction.”

 

Royal Auping

Auping has worked for 130 years on solutions in the area of sleep and the power of rest. Our conviction: a well-rested world is a better world. Sustainability, design and innovation are our main drivers. A good bed base is extremely important because it guarantees the right level of support and ventilation, ensuring a good night sleep. 
During the development process we pay attention to all relevant product details in order to maximize your sleeping experience. One of these is preventing noise generated by the bed construction.

Therefore, we invested in the Sorama CAM64 acoustic camera to enable our product development department engineers to analyze in detail what happens with the bed construction when in use. The resulting visualization of noise is giving us knowledge and insight resulting in silent beds, bed surrounds and furniture. Not only when it’s brand new, but during the complete lifetime of Auping products as well. 

 

Cooler Master

Cooler Master chooses to make their products even quieter by working with Sorama’s sound camera, a kind of thermal camera for sound. Sorama's solutions provide unmatched precision, ease of use and accessibility. As a result, Cooler Master obtains unprecedented insights into sound and vibration characteristics of their products, allowing them to further improve and validate their designs.

 

Electric screw driller

A commercially available screw driller makes noise caused by the electric power source induced vibrations. With the Sorama Scan M a first analysis of a free rotating screw driller was performed in an office environment. This means these results were not obtained in an anechoic chamber, but in an open space office.
