In this category, we will post free sound effects when writing letters on a blackboard using chalk. The scenes in the classrooms of elementary schools, junior high schools, high schools and so on are often used when using blackboards. What I want to use at that time is the sound effect of chalk written on a blackboard. Just by having the sound effects when writing letters with chalk, you can direct the air you are teaching in elementary and junior high schools at once. The sound of chalk on a blackboard is perfect for drawing in class in a classroom.
