A low hum in Purmerend, The Netherlands
A very low-frequency humming sound, only hearable when inside. Inside my home, my car or at someone elses home or inside a building around my hometown. It's only hearable when it's quiet. Sometimes it's at a constant volume, but most of the times the sound becomes alternately loud and soft with a constant regularity. It's very penetrating and anoying. There are days when the sound is gone, but 9 out of 10 days it's there. No
