Sorry guys for the delay in my response, I run a very busy business. My ears settled back 1-2 days after the exacerbation. My noise trauma caused 4 symptoms: 1. tinnitus, 2. abnormal "tinny" hearing, 3. hyperacusis, and 4. a pressure-like discomfort felt deep inside the ears. Well, the...

Another update..... Today my ears are definitely the worst they have ever been in terms of tinnitus volume, discomfort, and hearing distortion (although that could just be the tinnitus volume on top of my hearing). This could be a coincidence as the severity does drift around but Sunday evenings...

Thanks. Putting LEDs together is very simple DC circuitry. Unlike most DC devices you need to give them a set current rather than a particular voltage. An LED driver has terminals for your AC input and positive/negative terminals for the DC output to the LED. Most will have another couple of...

Within the box are two LED constant current drivers and a flashing circuit. It looks more complicated than it is in reality, I broke the screw connectors off the flasher (whoops) and had to open it up and solder directly to the circuit board: With LEDs you need a constant current driver, for...

I'm trialling it with a 10sec on/10sec off cycle at the moment. I've got one 940nm and one 850nm chip (who knows what is best!) and I turn the headset around half way through. The duration of the session is limited by comfort levels. Note that these are very high output chips, they consume...

For anyone interested, I attached each LED chip to a heatsink: I drilled a hole in a cheap pair of earmuffs: And attached the heatsink to the earmuff: The finished unit (note that the electronics box didn't need to be that big, it's just what I had available):

Sorry, I've been sick with a cold. These chips are around US$150 each. I just built a headset with a chip on each side and heatsink. I added a flasher circuit so that I can have them cycle on and off at whatever frequency. They put out a lot of IR! You instantly feel a huge amount of heat, not...

This is what I'm going for: http://docs-asia.electrocomponents.com/webdocs/11b1/0900766b811b1e33.pdf I'm getting one each of the highest output 90deg angle units in 940 and 850nm. These produce around 26 and 21 watts actual radiant intensity output. The reason that I'm going DIY is not to save...

I'm not worried about power consumption, I mean a LED chip being sold with an efficiency of 7% is not a good reflection on its quality.

The LED arrays are additive to some extent because the radiation field from each chip overlaps to a large extent. I decided against the Ebay Chinese ones though because they are very low efficiency (and of questionable wavelength too no doubt). I'm going to try some quality high output ones in...

If anyone is interested in DIY you can get high output IR (eg 850 or 940nm) LED chips such as this: http://www.ebay.com/itm/1w-3W-5W-10W-20W-30w-50W-100W-940nm-Infrared-IR-High-Power-LED-Light-Lamp-DIY-/261898554043?var=&hash=item3cfa5ecabb:m:mvLk0nMum89PMJt6ENXUemg Add a LED driver and a...

Thanks, I thought they looked a bit suspicious with the claimed power output, particularly when they also claim the battery lasts for hours. I looked up the stats on another similar unit and the pulse width was listed as 100ns, so in truth very short!

@Bobby B What do you think of these relatively cheap higher powered devices such as: http://www.pulselaserrelief.com.au/shop/PulsedLowLevelLaserTherapy This one has a 25W output and you can get it with a probe set but none are made for in-ear use.

I don't mean a full 10+W on the cochlea alone at close range, I mean externally applied like Bobby B described. How are you going to apply your LLLT direct to the cochlea as you describe? Have you ever looked in someone's ear at the eardrum? The external ear canal is not straight, and it can be...

I agree we need to look at higher powered sources (like 10 or 20W). Partly from the above article showing low tissue penetration when you are talking centimetres of tissue, but also from my own experience. I am an eye surgeon and I am familiar with using lasers on tissue on a daily basis...
