Creating Sound of EV

Creating Sounds for EV 
Let's take a detailed look at the various meticulously crafted layers that are a part of THOR AVAS and understand better how each of them works:

The Engine Simulation Layer

The Engine Simulation Layer comprises components of synthetic data that are generated using oscillators to recreate an engine's realistic sounds in AVAS electric cars. High frequencies are removed from the layer via filtering, leaving behind a tonally grounded base. Because of this process, the engineers at THOR AVAS are able to imbue the sounds with a particular atmosphere and synchronize them with the layers of additional notification, both of which are constructed on the tonic note. At all target frequencies, the result is a pure, dynamically rich sound unique for each package, with no unwanted sonic distortion.

The Additional Alert Layers

The additional alert layers produced by THOR AVAS are made up of melodic sequences that are either based on synthesized samples of plucked instruments or processed samples of bells and integrated into AVAS electric scooters and AVAS electric mopeds. These AVAS audio layers are included in the AVAS sound package and can be used at 10 kilometers per hour (approx. 6 mph). They continue to gain intensity and volume up to a speed of 40 kilometers per hour (approx. 24mph), where the announcement character peaks, reaching a maximum range of AVAS dynamics. The note Sol (G) of the third octave, which resonates at a frequency of approximately 1600 (1568) Hz, is used to determine the tonic. As a result of the short duration of the samples and the relatively fast "attack" of these instruments, they are plainly audible but do not sound harsh or intrusive to the human ear and do not have a significant impact on the overall AVAS dynamic.

The Vehicle Acceleration/Deceleration Layer

Additional non-musical layers that make up the vehicle acceleration/deceleration layer bring additional attention to the moment when the vehicle is accelerating. Furthermore, it provides "feedback" to the driver regarding the acceleration time. The AVAS audio data collected for this layer comes from an extensive sonic palette ranging from the foundational sounds of small motors to the movements of large industrial turbines, depending on the desired intensity level. A pedestrian may be alerted by the sound of a growing hum sampled from the mechanics of a turbine or a whistle, both of which are immediately associated with the sound of an accelerating engine. During acceleration, the layers are engineered with the package's original electric vehicle sounds using THOR AVAS' patented technology, which creates a pleasant AVAS soundtrack that is harmonious and noticeable. As the car moves, accelerates, decelerates, starts, and stops, the solution can accurately replicate the sampled audio in real-time synchronization with the movements.
