I work in a Dilbert cubicle style office environment, and there is always an irritating level of noise around: computers buzzing, people talking, phones ringing, alarms alarming, etc. I am also a very social person, so I am easily distracted and drawn in by the conversations and joking going on around me. The employer has been gracious enough to supply everyone with a set of Sennheiser noise cancelling earphones (NoiseGard Mobile HDC 451). They are quite good and definitely reduce noise. When I put fresh batteries in and turn them on, they definitely reduce the level of ambient noise. However, they are quite old. I think that the technology has probably progressed since the time these were brand new. Also, they are the type that sits on top of the ear with a plastic flexible U bracket in between. I want to try something that either goes in the ear, or covers the ears completely. I started looking around in the stores. Soon I found a set of earbud type earphones in Anttila of the Philips brand. (Philips Active Noise Cancelling SHN 2500). I paid the 44 EUR, thinking it wasn’t too much and went home. I opened up the package, put the battery in, put them in my ears and turned it on. It was nothing like the Sennheisers at work. They did not reduce the ambient noise at all. In fact I heard more noise after turning them on. I heard a slight hissing sound plus the same level of ambient sound. When I put music through them and turned them on, they slightly amplified the music. They sounded OK, but they did not have the “active noise cancelling” that I was expecting. I started reading customer reviews about them in the Internet. Many customers said the same as what I noticed: they sound alright, but they don’t reduce noise – they only amplify the audio going through them a bit. What I also noticed was that the average price I was seeing was about 20 dollars, or about 15 euros. I paid 44 euros in Anttila. So I got ripped off 300%. Needless to say, I took them back and got my money back. After reading customer reviews, it looks like I might buy a pair of Audio-Technica ATH-ANC7 QuietPoint Active Noise-Cancelling Headphones, listed for about 100 dollars in Amazon.com. They seem to have very good reviews and many compare them favourably to the Bose model that costs 300 dollars. I definitely know the name Bose, which is associated with professional audio systems.
 Pretty soon I want to blog about how every article I have ever read about the “open office” style workplace has been negative, saying things like it reduces peoples’ productivity, increases stress, and it takes 15 or so minutes for a person to get over a distraction and get back into their work. Some of the studies use empirical evidence, such as looking at the amount of stress hormones in peoples’ urine or how they behave. This basically means that a large part of office type workplaces in Finland are bad for your health and therefore the people are much less productive than they could be. This doesn’t just mean Finland either – many countries use the Dilbert cubicles and some workplaces even go so far as to have totally open offices. For now, I have to make my head swim in music and “active noise cancelling”. One person at work actually uses a pair of Peltor ear protectors, which is what you use for chainsawing, grind-cutting metal, using a jackhammer and stuff like that.
I am thinking of making a motorcycle helmet type thingy with air ventilation or peltier air conditioning, noise reduction, with high quality stereo speakers. At least I can put my head in a closed office that way. As I write I am unsuccessfully trying to ignore a conversation next to me that has been going on for about 20 minutes.
