Innenraumgeräuschen

Innenraumgeräuschen, which translates to interior noise, refers to any sound perceived by occupants within a vehicle's cabin. These noises can originate from various sources and significantly impact ride comfort and perceived quality.

Common sources of interior noise include the powertrain, such as engine vibrations and exhaust systems. Tire noise, including road surface interaction and tire tread patterns, is another significant contributor. Aerodynamic noise generated by airflow around the vehicle's exterior, especially at higher speeds, can also intrude into the cabin. Furthermore, mechanical components within the vehicle, such as suspension elements, HVAC systems, and even rattling trim pieces, can produce unwanted sounds.

The perception and tolerance of interior noise are subjective and can vary greatly among individuals. Factors like the frequency, amplitude, and duration of the noise play a role. Automakers invest considerable effort in noise, vibration, and harshness (NVH) engineering to minimize these unwanted sounds. This involves using sound-deadening materials, aerodynamic design optimization, and careful selection and mounting of mechanical components. The goal is to create a quiet and refined cabin environment that enhances the overall driving experience. Addressing interior noise is a crucial aspect of vehicle development, directly influencing customer satisfaction and brand perception.
