Noise Reduction
Reading the news and found out there's a product called noise-reduction headphone. It seems to be quite amazing with that other sound could actually be blocked?! I have heard technology like that in some supre deluxe car which the car would be absolutely quiet by active cancelling the engine sound with physics like sound wave destruction.
I intend to get one as my room is too close to public in the place where I am staying. I searched from the internet after reading local news on technology, got to the shops for it, not trying but a heart of trust. It looks very simple and china-made (well, we should trust our mother land?!).
The small little device box which need an AAA battery to switch on. The volume does boast up (does it mean using big volume to cover noise?!) after swtich on. Anyway, the ear-plug type headphone got me sometime to adapt to. It works when music is on but not work when it was silent (you just heard the current noise from the headphone).
Happy about it? Abit dissapointment but at least it will be handy on the plane and during long trip for blocking out all the sound.

Have you already bought one? Dad used to bring home noise abatement devices from his office while still working in Towngas (workers in the factory might use them). There's also one pair I got from Virgin Air. The land opposite to us at Forfar Rd may start developing, so a pair of these things would be useful.
will bring it back for him to try
