Basically I’m going to buy a new TV. But one TV has Nicam sound quality and the other has Dolby. I want to know what sound Quality is better. Can anyone help mee?
Please ignore the previous answers for they are talking rubbish. Unfortunately, most shop assistants don’t know what they’re talking about either.
NICAM and Dolby are not different versions of the same thing so they cannot (and must not) be compared.
They are different: one is a system for broadcasting stereophonic sound on analogue television systems; the other is a noise reduction system for high-fidelity sound recording and playback.
NICAM is an acronym for “Near Instantaneous Companded Audio Multiplexing”. It is the system used since 1966 for transmitting stereo sound over the analogue terrestrial television system. The NICAM system was designed in such a way that a mono television receiver would still be able to deliver the full sound (that is left+right channels).
Dolby is the trademark of Dolby Laboratories Inc. in the USA. About 40 years ago Dr Dolby discovered a way to reduce the hiss that was (and still is) always present on magnetic tape recordings. The system does this by enhancing certain frequencies when the recording is made and then reducing the same frequencies when it is played back. At the same time this also reduces the noise and hiss which is unavoidably inherent in magnetic tape recording.
All audio recordings made in professional studios are done on tape (even if they end up on CD) and so the professional standard Dolby “A” system is still very much alive and well.
Some television programmes have their sound tracks recorded using the Dolby system and some television sets (but not all) can do the correct decoding. Unfortunately, it’s a waste of time and money.
The huge majority of tv sets are not capable of true High-Fidelity sound reproduction. Whatever the makers and salesman say, their loudpeakers cannot ever be good enough and still fit inside the cabinet. In the world of Hi_Fi, size really does matter. It’s a law of physics that clever electronics can’t fully overcome.
All “stereo” televisions will use the NICAM system when they’re receiving analogue transmissions (digital sound uses a different system), you have no choice in this. It is just the way that the televisions are made.
It is a sad fact that 99% of television sound does not qualify as “Hi-Fi”, however expensive the set is. If you listen to a concert on telly and then listen to the same piece on a record played on a Good Hi-Fi sound system (not a cheap “sound box”) you will notice a difference.
Therefore, paying extra for the Dolby system is mostly going to be a waste of your money unless you are also going to invest in a costly pair of proper Hi-Fi external loudspeakers.
You are better off spending your money on the television set that gives you the best picture. Make sure that you compare the same programme on each set that you look at.
While those different features are all well and good, the 5-10 watt speakers that manufacturers put in tvs are of the lowest quality possible. If you are really looking for superior sound, I would look into an auxillary sound system. A tv’s main job is to produce a crisp, colorful image, so I would make my decision off of that.
In my opinion mate, I’d go with nicam, and if you feel it’s not the quality you require it could be improved by adding a “Dolby” home surround system, whereas it doesn’t work the other way round.
Also, Preset Equalizers It are GENERALLY always built into almost all modern T.Vs.
QUELLE est la relation entre nicam et dolby
I personally think dolby is better.
i prefer nicam personally.
DOBLY IS BETTER THAN NICAM
