His main tools are recording devices (camera, tape deck, radar, sonar) used in an ongoing investigation of electricity, frequency, architectural space, and paranormal electronic interference.

He also collaborates with EVP researcher Michael Esposito, filmmaker Thomas Nordanstad, and with Graham Lewis (Wire) and Jean-Louis Huhta in the band OSCID.

Von Hausswolff is noted for creating sound works that "charge the air with subliminal force" using "drones, radio signals, and sonic frequencies".

Recent audio works include "800 000 Seconds in Harar" (Touch), "Matter Transfer" (iDeal), "The Wonderful World of Male Intuition" (Oral), "There Are No Crows Flying Around the Hancock Building" (Lampo), "Rats", "Maggots", and "Bugs" (all three on Laton), "Three Overpopulated Cities ..." (Sub Rosa), "A Lecture on Disturbances in Architecture" (Firework Editions), and "Ström" and "Leech" (both on Raster-Noton).

He is also the curator and producer of the sound-installation "freq out", shown at Moderna Museet (Stockholm), Henie-Onstad Center (Oslo), Sonambiente (Berlin), and other places.
