#DETECTION THEORY SERIAL#

In addition to recording the results, I decided to display the results using p5.js, a library that enables the communication between a p5 sketch and serial enabled device (Arduino).Ĭan create the same test setup by following these instructions.įor the SDT test, I decided to set the total number of trials to 20 with an even split between present signals and absent signals. Score for the hits, correct rejections, miss, and false alarms will go asīeeper is on and the button is pushed, you are in the hit rate zoneīeeper is on and the button is not pushed, you are in the miss zoneīeeper is off and the button is pushed, you are in the false alarm zoneīeeper is off and the button is not pushed, you are in the correct reject zoneĪ counter of +1 will be added to each category that the user falls in. The volume level recorded by the user from part 1 is used for the test. See the LED turn on as well as hear the buzzer. As statedĪbove, my SDT test will involve the user pressing a button for every time they Second part of the project is the actual setup of the test device. You can create the same hearing-threshold setup by following these instructions. The recorded values are averaged, and the corresponding potentiometer value is mapped from the range of (volume needs to be in bytes).

They would perform this task again but starting the potentiometer from the opposite end.

To accomplish this, we would have the user dial a potentiometer that controls the volume of a buzzer to the level at which they can barely hear the sound and hit the button sensor to record that value. Before a user can take this test, we first need to determine the user’s hearing-threshold because ideally, the volume level of the buzzer needs to be roughly-close to their threshold, a level at which that can barely hear the sound. The buzzer sound will randomly turn on or remain off for 1 second in duration at the same time the LED turns on. The LED will turn on and off at a constant rate. The test will involve a user pressing the button only when they see the LED turn on AND if there is also a sound from the buzzer. The first part of this project is to create a test device. Arduino Grove Beginner Kit with LED and Buzzer in the top left and button and potentiometer in the bottom left For this project, an LED, button, potentiometer, and buzzer sensors are included with the Arduino board therefore I decided to conduct an SDT experiment using light and sound and obtain the user’s input using the button sensor.

A user will only need to download the Arduino IDE version (1.8.13) to run their code with assigned pins to inputs/outputs to utilize the sensors.

I will be using an Arduino ( Grove Beginner Kit) that contains various sensors that are pre-connected right out of the box and a USB-cable to connect the Arduino device to your PC therefore, I did not need to any wiring or retrieve any additional hardware.
