PA Designer : Project
This is the second challenge within the Robotics with GoPiGo and Python Curriculum.
Your task is to program your robot to alert a person with a hearing impairment to visiting house guests.
Learn how to use the Loudness Sensor alongside Jupyter Notebooks.
2. Make a Directional Sound Chamber
Using a sensor mount and the mounting holes in the chassis, mount the loudness sensor upright on the top of our robot.
Using whatever craft materials you have to hand or even Lego let’s make a directional sound chamber to shield the sensor from sound from behind and focus it more on the sound in front of it. This will make it easier to hear the doorbell in a noisy environment.
Test the effectiveness of your chamber. Re-run the 10 second data analysis task from the LEARN section a number of times, with and without the chamber, to compare the effect of ringing the bell immediately in front of and behind the sensor.
Try out different materials to see which ones work most effectively for you. What materials give you the best soundproofing from behind? What do you think makes these materials good for soundproofing?
