Active Sound Design (ASD) is a feature in many new BMW models that enhances the engine sound by playing engine sounds through the car's audio system. ASD was first launched on F10 models and was designed to address the issue of modern cars being too well sound-isolated, making it difficult to hear the engine. While some BMW fans have complained about ASD, others prefer the enhanced sound it provides. The system works by generating specific waveforms to make up for deficient frequencies in the drivetrain harmonics, resulting in the desired cabin sound. ASD can be customised to the driver's preference, with options to adjust the intensity and choose between Sporty, Balanced, or Reduced modes.

Active Sound Design (ASD) is a standard feature in many new BMW models
BMW is not alone in this endeavour, as car audio manufacturers such as Harman Kardon dedicate significant resources to noise management and partner with car companies early in the development cycle of a new vehicle to create the optimal cabin experience. This involves analysing the engine sound at all RPMs and identifying specific frequencies (harmonics) that are deficient.
ASD works by generating a waveform similar to a sine wave at the specific frequency where a drivetrain harmonic is missing. If the deficiency is in the exhaust area, a tone from the rear speakers is generated, and if it is engine-related, a tone from the front end of the car is produced. The end result is a cabin sound that the car manufacturer intended to achieve, which previously would have been done mechanically.
While some BMW enthusiasts have complained about this feature, it has improved since its inception and now offers a more accurate and efficient aural experience. Users can also adjust the settings to change the intensity of the sound or turn off ASD completely if they prefer to hear the natural engine noise.

ASD enhances the engine sound by playing engine sounds through the car's audio system
Active Sound Design (ASD) is a feature in many modern BMWs that enhances the engine sound by playing engine sounds through the car's audio system. This technology was developed in response to advancements in fuel efficiency and safety, which resulted in quieter engines and stricter regulations for exhaust noise. ASD aims to maintain the aural experience associated with driving a powerful car.
The system works by analyzing the engine sound at various RPMs and identifying specific frequencies (harmonics) that may be deficient. When a deficiency is detected, an amplifier generates a waveform similar to a sine wave at the missing frequency. The tone is emitted from the front or rear speakers, depending on whether the issue is engine-related or in the exhaust area. This results in a cabin sound that car manufacturers desire, which previously would have been achieved through mechanical means.
ASD has evolved since its initial launch, with improvements in efficiency and accuracy. While some BMW enthusiasts prefer to disable ASD, others appreciate its ability to enhance the driving experience. The feature can be customized to suit individual preferences, with options to adjust the intensity and choose between Sporty, Balanced, or Reduced modes.
The inclusion of ASD in BMW models varies, with some reports indicating its presence in F10, F32, 2 Series, 3 Series, and 4 Series vehicles. However, there is inconsistency within model years and specific models, suggesting that ASD may be optional or introduced at different production stages.
ASD plays a role in noise management, addressing undesirable cabin noises that can result from traditional methods used to make vehicles sound "sporty." By partnering with car audio manufacturers early in the development cycle, BMW can create a tailored cabin experience that balances the engine sound and driving experience while potentially reducing weight and development costs.

ASD can be adjusted or disabled via the 'Car' menu in the infotainment system
Active Sound Design (ASD) is a feature in many BMW models that enhances the engine sound by playing engine sounds through the audio system inside the cabin. ASD was first launched on F10 models and was designed to address the issue of modern cars being too well sound-isolated, resulting in a lack of engine noise. While some BMW fans have complained about ASD, the brand argued that it was necessary to maintain the aural experience.
Over time, ASD has improved in terms of efficiency and accuracy, and users now have more control over the settings. It is possible to adjust or disable ASD via the 'Car' menu in the infotainment system. To do this, go to the 'Car' menu, then to 'Settings', followed by 'General Settings'. Scroll down to 'Engine Sound' and adjust the Active Sound Design intensity to your preference. The default setting adjusts the ASD intensity depending on the driving mode, but you can also set it to 'Sporty', 'Balanced', or 'Reduced'.
ASD works by injecting fake engine and exhaust noise into the cabin through the speakers. It involves analysing the engine sound at all RPMs and identifying specific frequencies (harmonics) that are deficient. An amplifier then generates a waveform similar to a sine wave at the specific frequency where the drivetrain harmonic is missing. If the deficiency is in the exhaust area, a tone from the rear speakers is generated, while a tone from the front-end of the car is generated for engine-related deficiencies.
Some BMW owners have expressed mixed reactions to ASD. While some prefer the enhanced sound it provides, others have chosen to disable it, claiming that the real exhaust note sounds better. Additionally, some have noted that ASD can be headache-inducing and that the car is much quieter without it, allowing for easier conversations at freeway speeds.
