Lennox XP25 heat pump uses Precise Comfort technology to offer exact temperature, while boasting efficiency ratings of 23.5 SEER & 10.20 HSPF.Julian Treasure takes the stage at TEDGlobal 2. Julian Treasure cares very deeply for your ears. That’s why he’s given TED talks like “The 4 ways sound affects us” and “Why architects need to use their ears.” Treasure is on a mission to make policymakers, engineers, architects and, well. Julian Treasure: Shh! Sound health in 8 steps. To this end, Treasure’s The Sound Agency has teamed up with Biamp Systems to create a whitepaper called “Building in Sound,” a look at the data linking sound and well- being.“This paper is based on exhaustive review of academic papers, and reports from national governments and multinational bodies, going back some 4. In this study, they calculate the financial cost of lost work days, healthcare treatment, impaired learning and decreased productivity due to noise. The total they came up with is staggering, considering they’re looking at just one continent. Each year, noise pollution takes a day off the life of every adult and child in Europe. This same study also looked at the cost of noise pollution in terms of lost life expectancy. Shockingly, they determined that every 3. European’s collective life expectancy — averaging to a day per person. If you can hear someone talking while you’re reading or writing, your productivity dips by up to 6. In a classic study published in the British Journal of Psychology in 1. Another classic study found that noise in the office also correlated to increased stress hormone levels and a lower willingness to engage with others.

Entrez dans l'univers de Pixie Décibels, là où foisonnent culture et folie musicale! Chronique sciences et astronomie avec Jean-Michel Gastonguay, Directeur de l. I thought ACME Tornado 2000 Whistle was the loudest in the world? I have never actually heard of the Valkeen or Flox Blast. While romantic love isn’t something I can empathize with most of the time, I’m prone to falling for Bonnie and Clyde fantasies like a sucker. Fully fledged: Gosling’s credits include The Notebook, Drive, Crazy Stupid Love and The Ides of March. Leading man: Ryan Gosling. According to Sound Agency case study, when sound masking technology was used in an office, there was a 4. The average noise level in many classrooms is not just associated with impaired learning — but with permanent hearing loss. Noise can deeply affect learning too. The WHO recommends a noise level in classrooms akin to that you’d find in a library — 3. However, a study in Germany found that the actual average noise volume in classrooms is 6. As Treasure outlines in this talk, for a student sitting in the fourth row of a traditional classroom, speech intelligibility is just 5. A 2. 0 decibel increase in aircraft noise is enough to delay a student’s reading level by up to 8 months. A study published in the American Journal of Epidemiology in 2. The Netherlands, Spain and the U. K. They found that aircraft noise was associated with impaired reading comprehension. A study of teachers published in the Journal of Speech, Language and Hearing Research in 2. Because as the environment gets noisier, we speak more loudly. The average noise level in some hospital wards not only impedes healing — but could legally require hearing protection. The WHO recommends noise levels in hospital wards to stay around 3. But a study in the US found the average noise level in hospital wards is actually closer to 9. U. S. Sleep is crucial for patient recovery, and yet with the constant beeps, tones and shuffling, the body feels that it is under threat. Not to mention that staff errors increase the greater the level of distracting noise. Germany have been explicitly linked to traffic noise. Treasure found this alarming fact in a 2. Environmental Protection UK. Noise pollution may possibly even contribute to crime. When the city of Lancaster, California, installed a sound system featuring birdsong along a half- mile stretch of a main road, there was a 1. The Wall Street Journal. Similarly, when the London Underground started playing classical music at a crime- heavy station, robberies fell by 3. The Independent. Below, an infographic further outlining the problem. The decibels of popular referee whistles. What is your favourite referee whistle? How do you pick your whistles? And what makes a whistle good? I like whistles with a sound other referees don’t have. The Fox 4. 0 Pearl has that in The Netherlands. That reminds of a situation during last season. I officiated with a blue Pearl version of the Fox 4. Usually people ask me afterwards something about a situation or just say thanks for refereeing. But a man stepped forward and began talking about that unique sound of the whistle. Yeah, it was a colleague who was off duty that weekend. I’m wondering if he found one, because (most of) the Dutch sport shops only sell the Fox 4. But it kept me thinking: how do referees pick their whistles? I’d love to know what your favourite one is. Recently stumbled on this picture below. A loud sound is important for me and Refsworld, an Australian referee shop, did some nice tests with a decibel meter. Whistle comparison by Refsworld with decibel meter. Valkeen – 1. 27. 6 d. BFlox Blast – 1. 27. BAcme T2. 00. 0 – 1. BFox Classic – 1. BFox Mini – 1. 24. BFox Sharx – 1. 23. BFox Eclipse – 1. BAcme 8. 88 – 1. 16. BFox 4. 0 Caul – 1. BSource is Refsworld – check their whistles. For your information, some facts about decibel levels. A motorcycle is 1. B, a loud rock concert is 1. B and pain starts at 1. B. Decibel meter at whistle test was at 2 meters, so players better not come close to the referees with the loudest whistles.
