Why explosions are loud




















Small earthquakes are not unheard of in New Hampshire. Gloria Oladipo. Mon 11 Oct Others wondered if the boom came from a meteorite or a plane. Soon afterwards, his fire department received numerous calls about the boom. Headphones, regular TV sets, and systems with a pair of speakers and no subwoofer are referred to as 2. The number before the decimal represents the number of full frequency range channels—so, regular front speakers, rear speakers, and so on. The number after the decimal represents the number of specialized, low frequency channels—output to subwoofers.

So, if you add a single subwoofer to 2. Add in rear surround speakers and a center channel front speaker, and it becomes 5. Add in two additional side surround speakers and you get 7. Some systems feature an additional pair of directional surround speakers, resulting in 9. Dialogue is pumped through the center channel, labeled with a 2 in the above diagram. As a fun aside, you can unplug the wire to your center channel speaker while watching a movie or sporting event and the voices of the actors or announcer will vanish.

The audio engineers expect you to turn it up to hear the dialogue and then get rocked right out of your seat when that unexpected car bomb goes off. The phenomenon is radically more pronounced in action films and practically nonexistent in sources like sitcoms aside from annoyingly loud commercials. In , for example, audio engineers released a paper highlighting how movies such as The Matrix had a range of 25 units from the loudest to the quietest moments where as sitcoms like Friends had a range of only six units.

Subjects often feel fear or distress after the incident. People over the age of 50 are most likely to experience exploding head syndrome. Women are at a higher rate of experiencing it than men. It has been reported in people as young as 10 years old.

Exploding head syndrome is thought to be highly connected with stress and extreme fatigue in most individuals. What actually causes the sensation in individuals is still unknown, though speculation of possible sources includes minor seizures affecting the temporal lobe, or sudden shifts in middle ear components.

As exploding head syndrome is not dangerous, and does not have a drastic effect on sleep, many individuals do seek help for their symptoms. It will first be necessary to consult with a sleep doctor regarding your sleep and medical history to ensure that what the individual is experiencing is actually exploding head syndrome and not something else.

Similar experiences have been known to be brought on by certain medications or drugs. Exploding Head Syndrome may lead to secondary insomnia. One medication that has been used to treat exploding head syndrome is clomipramine, a tricyclic antidepressant.

If stress is causing the episodes, it is advised to either seek to clear the problem. This could include reading, yoga, relaxing music or a hot bath before bed. These steps have also demonstrated to have positive effects in achieving quality sleep in general.

If the disturbances are the result of sleep deprivation , it is recommended to institute a more balanced routine that includes a minimum of 6 hours of sleep per night.

If sleep deprivation is being caused by other sleep related disorders , these should be evaluated. I had this happen last night, its not the first time. Within moments of falling asleep, I hear fizzing, see bright flashing lights. I also feel like someone is pulling the bedding off of me. The worse is the jerking movements and pulsating lobes. I also feel i cannot move as i try to awake, what seems like a polar opposite of the real life surroundings, fighting to open my eyes but seeing if that makes sense?

I tend to get up, albeit confused hot and sweaty with palpitations. I have issues sleeping as i tend to wake up probably 50 times a night or more. I have seen a doctor to be diagnosed with sleep apnea, but do think that is a cause as i am a horrendous snorer. I installed an app on phone that records sleep patterns by recording the breaks in silence and the noise of gasping for air and my ex- partner had even told me i stop breathing for long periods and then start up again.

Hearing it for myself it sounds pretty horrific. Regarding the buzzing and fizzing and flashing lights, it is random and starts almost as soon as i drift off, it happens often and can start again quickly even when I go back to sleep within that period.

Tippett says that unless you have had a particularly rich or spicy meal and can trace your toilet habits to that, regular explosions usually signal that the gut is not absorbing sugars and carbohydrates well, so that they remain in the gut and ferment.

If you want to increase your good gut bacteria, nutritionists generally recommend eating plenty of fibre from foods like fruit, vegetables and whole grains. Tippett says a pale floater could also signal inflammation and inadequate liver function.
