alarm 1 about 50 to 1500hz

alarm 2 it has hz about 50 to 1500 hz 

alarm 3 50 to 1000hz

step 2 the car honking sound has about 100 to 800

step 3 i think that self driving cars need microphone

1. • Consider the placing microphone inside the door panel , in a spot that is somewhat insulated from external wind. The doors themselves provide a certain amount of sound insulation.

2. Near the Rearview Mirror :

   • Another potential spot is near the rearview mirror on the inside of the windshield. This area is generally protected from wind, and it's positioned where the microphone can still capture sounds both inside and outside the vehicle.

3. Windshield Vents or Seals :

   • You could also hide the microphone behind a windshield vent or near the weatherstripping along the windows. These areas will help shield the mic from turbulent airflow while still being sensitive to external sounds.

Additional Considerations:

• Directional Microphone : Use a highly directional (shotgun) microphone to focus on sounds from specific directions. This can further help minimize unwanted noise from the environment, including wind.
• Windshield or Windscreen : A microphone with a windshield (a foam or furry cover) can help reduce wind noise, even if the mic is exposed to some airflow.

These placements, combined with directional microphones or noise-canceling technology, should help reduce the impact of wind noise on the microphone's ability to detect external alarms.
