Scratching ASMR uses nails on textured surfaces, fabric and the mic itself. These channels feature it often, usually in fast or layered trigger videos.
Scratching channels feature it often, usually next to tapping and other texture triggers. Many of these creators favour long nails and a close or binaural mic, since the trigger depends on fine detail.
Uploads often focus on one material at a time, such as a foam mic cover, a textured phone case, fabric or the bristles of a brush. Long nails give a sharper, more detailed scratch, while fingertips and soft tools sound gentler. Some creators scratch directly on the mic, which makes the sound much closer and louder than scratching an object nearby.
