## 3 Simulation and Experimental Results
Following the configuration of settings in the Frequency plane within the audio file, adjustments were made to the dB difference between the peaks in the Significant Frequencies and the peak levels in the non-obvious range. This adjustment was carried out using a technique called Compression in Digital Arrangement processes. By employing this process, the dynamic range within the structure was regulated. Furthermore, by rendering the peaks at specific frequencies in the audio file distinguishable from one another, the sound was ensured to evoke a consistent sensation across all systems, as depicted in Figure 15.  
In Figure 16, the single-channel audio file resulting from the arrangement operations conducted on the audio file exhibits a structurally smoother profile, effectively resolving the out-clipping problem observed in the Merge state. This arrangement guarantees that the audio file can be played as loudly and cleanly as possible across multiple systems. Figure 17 displays the results of computer simulations alongside the FFT graph. Furthermore, acoustic and electrical tests were conducted in a fully equipped quality laboratory to corroborate the simulation outcomes. The AVAS device, as illustrated in Figure 18a, was connected to a DC voltage source and a calibrated acoustic test device. In Figure 18b, the placement of the AVAS device and the measurement microphone in the sound-isolated acoustic room is depicted, maintaining a distance of 2 m, as stipulated in  
Figure 16: “Downmixing Merge” file represents the audio signal after arranging operations, and the “400–500 Merge” file represents the audio signal converted to a single channel without arranging.

In Figure 18c, the FFT graph of the AVAS system utilizing the designed digital horn sound is measured in an anechoic chamber approved by The Scientific and Technical Research Council of Turk'sive, National Metrology Institute (TUBITAK UME). It is evident from

Furthermore, the designed sound falls within the range specified in the regulation (106.1 dB), indicating successful compliance. The digital horn sound obtained as a result of this study, which was tested and approved in both the simulation environment and the laboratory, is shared as a Supplementary File under the name \"Horn_Sound.wav\". The file named \"Horn_Sound.wav\" represents the audio output generated by the suggested program in this study, while the file named AVAS_Sound.wav corresponds to the standard AVAS sound. The audio signal illustrated in Figure 19a exhibits peaks at specific frequencies with a more uniform distribution and a well-balanced tonal structure. This design ensures a cleaner and more effective sound experience, particularly in scenarios where a distinct tone is required, akin to a mechanical horn. Moreover, reduced fluctuation and noise in low-frequency regions enhance the signal's clarity and purity, minimizing unnecessary frequency interference. The sharpness and prominence of the frequency peaks emphasize the signal's strengths in certain frequencies, reinforcing its harmonic structure. While the audio signal in Figure 19a benefits from careful digital design, higher dB levels, and controlled characteristics, the signal in Figure 19b demonstrates unnecessary frequency fluctuations at lower dB levels. Consequently, the superior tonal quality and controlled structure of the signal in Figure 19a make it the preferred choice for high-quality horn sound.
