As you press accelerator deeper the sound increases which shows you rev limit & thus speed + force forward 

Key Factors of V12 Sound

The unique, high-pitched "scream" of many performance V12 engines is a result of several factors: 

• High Revs: V12s often have high redlines, increasing the frequency of the sound waves.

• Even Firing Order: The cylinders fire in a very smooth, consistent sequence (even firing order), which results in a continuous, linear sound profile, as opposed to the "burble" of an odd-firing V8.

• Cylinder Count: More cylinders at a given RPM mean more frequent combustion pulses, which directly increases the fundamental pitch of the sound.

Generating noise from air primarily happens through turbulence, where airflow disruption at obstacles (like dampers, bends, or even tire grooves) converts air's kinetic energy into sound waves, and through sudden displacement, like whistling or clapping, pushing air molecules rapidly. This "aerodynamic noise" is crucial in HVAC systems, musical instruments (wind instruments), and even tire sounds, involving pressure changes and sometimes resonance. 

How Air Generates Sound

• Turbulence & Discontinuities: When air flows over or through a sharp edge, a change in direction (elbow), or a partial blockage (damper), the smooth flow breaks down into chaotic eddies (turbulence). This turbulence creates rapid, localized pressure fluctuations, which are sound.

• Vibration Excitation: Turbulent air can vibrate nearby surfaces or excite resonators (like the air in a bottle), which then radiate sound efficiently, as seen in wind instruments.

• Sudden Displacement: Rapidly moving or displacing air, as in a whistle, clap, or a jet of air, pushes molecules into waves, creating audible sound.
 
Common Examples & Sources

• HVAC Systems: Fans, dampers, grilles, and ductwork create noise from airflow turbulence and mechanical vibration.

• Wind Instruments: Air blown across an edge (jet-edge) or through reeds excites air columns, creating specific tones through resonance.

• Vehicles (Tires): Air pumping out of tire grooves as they leave the road creates pressure waves, contributing to road noise.

• Aerodynamic Sound Generators: Devices use intersecting air jets or high-velocity jets from nozzles to intentionally create noise, often for testing purposes. 

Key Factors

• Air Velocity: Higher speeds increase turbulence and noise.

• Geometry: Sharp bends, abrupt changes, and constrictions in ducts or passages increase noise.

• Resonance: Pipes and cavities can amplify certain frequencies, turning subtle air movements into loud tones. 

• Acoustic Vehicle Alerting System (AVAS): At low speeds (typically below 18.6 mph), EVs are required by law in some regions to emit a pedestrian warning sound (PWS) because the motors themselves are nearly silent. This sound is often described as a low hum, whir, or a futuristic "hovering" noise, which can be perceived as muffled compared to a traditional engine rumble.

• Thermal Management Systems: EVs have active thermal management systems to keep the battery and motor at optimal temperatures. Fans and pumps for the liquid cooling system can run while the car is parked or driving, creating a humming or whirring noise that might sound muffled.

• Sound Insulation and Design: Manufacturers heavily insulate EV motors, often using liquid cooling within thick metal casings, which inherently muffles the internal mechanical noises. The general quietness of EVs makes other previously masked sounds (like wind or tire noise) more noticeable. 

FUNCTIONAL SOUND

Generating realistic V12 engine sounds from airflow involves manipulating the air's pressure, frequency, and resonance, much like an organ or a wind instrument. The actual sound is an intricate result of complex fluid dynamics and the engine's mechanical components. 

Methods for Generating V12 Sound from Airflow

• Aerodynamic Resonators: Ferrari has patented a system for electric vehicles that uses precisely designed aerodynamic resonators to replicate engine sounds from the airflow around the car. This method involves channeling air through specific pathways to generate desirable frequencies and tones that mimic a combustion engine's acoustics.

• Exhaust System Design (Acoustic Tuning): The primary method in traditional combustion cars is the exhaust system. Engineers use specific pipe lengths, diameters, and components (like X-pipes and mufflers) to tune the sound.

• Pipe Length and Diameter: Similar to an organ, the physical dimensions of the exhaust system dictate the pitch and tone of the sound waves produced by the exiting exhaust gases.

• X-Pipes: These components help to blend the exhaust pulses, which can create a smoother, higher-pitched, more "exotic" sound characteristic of many V12s.

• Megaphones: Placing a megaphone at a specific point in the exhaust system can enhance the pitch and volume.

• Intake System Tuning: The intake side also produces significant noise. A performance air intake system or modifications like a "sound tube" can channel more of the engine's natural induction noise into the cabin, enhancing the aural experience. 

Digital Sound Simulation

Modern vehicles, especially quiet hybrids and EVs, frequently use Active Sound Design (ASD) systems to create or enhance the engine sound inside the cabin, or even outside the car. 

• Speakers: The sound is generated digitally and played through the car's existing speaker system.

• Real-time Simulation: Advanced software, like the "Engine Simulator" project, uses real-time fluid dynamic simulations to accurately produce sound and performance data based on the engine's current operation.
