Television: The Sound of Entertainment

Introduction:

Television, also known as TV, has been a popular medium of entertainment for decades. It has revolutionized the way we consume media and has transformed the world of entertainment industry. This article explains the phonetics, i.e., the sound of television, the origin and its evolution over the years.

The Phonetics of Television:

The phonetics of television is the study of the sounds produced by electronic media broadcasting systems. The TV broadcast sounds are made up of speech, sound effects, music and silence. It is a combination of phonemes and acoustic features that convey meaning to the viewer. The original television used an analog signal to transmit the sounds and images. The sound signals were transmitted using VHF (Very High Frequency) and UHF (Ultra High Frequency) bands. With a combination of VHF and UHF, the television broadcast transmitted the voice and sound to the viewer’s TV sets. In the 21st century, with digitalization, television transmission has evolved. Digital television has improved the sound quality to a great extent. Television’s digital signal is transmitted in packets of data. The digital signal can carry more data, which allows for a higher sound quality compared to the previous analog signal transmission.

The Origin and Evolution of Television Sound:

The first practical TV system was introduced by Philo Farnsworth in 1927. However, it wasn't until the 1940s that television became widely available to the public. In the early days of TV, the sound was broadcast in mono (monaural) sound. Mono sound is a single-channel recording of sound that is produced by one microphone or one sound source.In the mid to late 1950s, stereo sound broadcast in television arrived. Stereo sound is a two-channel system that separates the sounds, i.e., two different sound sources recorded separately in two different channels. The viewer received a more realistic sound experience through stereo sound. The stereo sound made the listening of the soundtracks clearer and more defined. The 1980s saw an innovation in sound systems - Surround sound. Surround sound is a multi-channel audio system that immerses the viewer in the sound experience. The sounds are distributed into six channels: left and right front, left and right rear, and left and right center. Surround sound became popular in movie theaters but later became available in home theaters.

Conclusion:

The sound of television has undergone various changes and advancements throughout its development. From the first practical TV system introduced by Philo Farnsworth to surround sound systems, audiences have witnessed a considerable improvement in the sound of TV over the years. Today, television sound quality has reached new heights with new state-of-art sound systems. Undoubtedly, television's phonetics will continue to evolve, and we can only imagine what the future holds for this exciting medium of entertainment.
