Recently I came across an article on the phenomena of “The Hum” – a low-frequency sound heard by people across the globe. The hums are often given their location’s place name, such as the Taos Hum of New Mexico, the Auckland Hum or the Windsor Hum. While these sounds are clearly heard, no one seems to agree on the source of the sound: It could be produced by electrical equipment, an unfamiliar animal sound (such as the toadfish), the Jet Stream shearing powerline posts, volcanic eruptions, lightning static, ocean wave vibrations, or internal biological auditory signals.
If you stop and listen, there are sounds everywhere. But The Hum is not tinnitus, which has a much higher sound frequency. I’ve had tinnitus for years; when it’s quiet, I can hear up to eight tones of ringing in my ears. It’s something that affects around 15% of the population, but the only time it really becomes an issue is if it triggers a fight-or-flight response in a person – I’ve heard that the more you focus on the ringing, the more you hear it (the more it bothers you). In almost half of the people who have tinnitus, it can lead to phases of anxiety or depression, likely linked to that psychological fear response. Some people don’t even realize they have tinnitus – they automatically, subconsciously distract themselves with sound (music or television being common tactics). The causes of tinnitus vary, but in my case, I know exactly when it started: I was flying from London to Glasgow, and I had a head cold. The flight was just at that altitude where your ears almost pop, and it was excruciating. I can still hear fleas sneeze and “tell you if they’re male or female”, but the ringing is always present – I just ignore it for the most part. I hear so well that I sleep with earplugs each night – otherwise, I can hear electricity in the walls, and a battery charger at the far end of our home sounds like a car alarm to me!
Have you heard The Hum? Do you have tinnitus, and if so, does it bother you in any way or are you able to ignore it?
