All people are living a sophisticated life with all forms of advancements. A major part played in their luxury lifestyle is technology and gadgets. We can’t see a house without a fridge, mixer grinder, laptops, smartphones, and smart tv hanging on the wall with more advanced home theatre surroundings. More precisely, people like to enjoy their weekends with a bucket of popcorn and a feel-good movie, which will give them the theatre effect. So people are ready to buy the best home theatre to get a real-time experience.
HOME THEATRE – THEATRE EFFECT
As I already mentioned, people want to watch a movie with a theatre effect. Theatre is always famous for its sound effects. But with the help of today’s technological advancements, it is possible in normal homes with the help of a home theatre speaker. In theatre, a major disappointment is a privacy, we can’t expect privacy in theaters. Our privacy is preserved with the help of home theatres.
SOUND- SPEAKER- HOME THEATRE
Before jumping straight to a home theatre. First, we should know about the sound. Sound is created with the help of a wave. When we speak we vibrate or disturbed the molecules or atoms which surround us and it reaches the listener’s ears with the help of the vibration. After reaching the listener’s ear, it vibrates the eardrum of the listener. then it is hearing. This is sound.
Later, we should know about the working principle of a speaker. Speaker consists of a coil, with the help of electricity it takes the input sound from the connected device whether it is TV or radio or smartphones or laptops, and so on, and it amplifies the sound and gives a good experience. The same principle is used in the home theatre. It is a low type of input from a TV and it takes into the main system of the home theatre and it amplifies or boosts up the sound and it gives stereo effect sound. This gives a theatre-like feeling at home. Here, we are secured with our privacy and have no issues.
VERSIONS OF HOME THEATRE
Types of home theatre available right now are 2.1, 5.1, and 7.1. Here 2.1 consists of 2 speakers and one subwoofer, 5.1 consists of 5 speakers and one subwoofer, and 7.1 consists of 7 speakers and one subwoofer. Here, I repeatedly used the word subwoofer, first we need to look into the function of the subwoofer. The movie is not only the conversation between two characters, it consists of songs, action sequences and background scores, and so on. Each sequence comes with various kinds of sound, or it even gives a mixture of sound. Sound varies according to the scene and screenplay. It may consist of high-pitched or low-pitched sounds. High pitched sounds are easily audible, but low pitched sounds won’t. For this purpose only we are having a subwoofer, it can track even the low-pitched sound and gives a real theatre experience. The above one is all about the sound and working principle of the speaker and home theatre.
HOME THEATRE AND ITS DEVIL SIDE
Everyone in this world likes to share the best parts of their association with technology and gadgets. But every advantage is having another disadvantage. Every gadget and technology has the capability to ruin our lives. Though we all speak about the tremendous use of laptops and their functions and at the same time it affects our health like the eye and radiation emitted from the laptop creates sickness in our body. Likewise, home theatre is also having the other side.
NORMAL HEARING RANGE
From our schools itself, we are all well known about the affecting nature of noise pollution. Though there are so many pollutants that exist in this world, they are visible and we can tackle them with a visible solution. But noise pollution is invisible, it is the great invisible destroyer of our life. Sound is the greatest thing in this world, it plays a vital role. with the help of the sound only we can able to speak to other person and convey our message. even though there are sign languages are present, with the sound we can easily convey our information. But that sound exceeds the limit, then it’s a problem.
Usually, a unit called Hertz is used to measure frequency. every sound has such frequency. A normal person’s hearing range is from 20Hz to 20,000Hz. If it exceeds then it creates damage to our eardrum. Then it leads to hearing loss. Even this hearing range can vary according to age. A normally young healthy man can hear the above-mentioned hertz, but the old man can’t. There are limited frequencies allowed for aged people and children because this may cause health issues.
CONCLUSION
This is applicable to the home theatre also, first, you should know about the healthy frequencies of the home theatre and follow them as it is. Then there is no problem. Even nowadays, the home theatre is having some technology to intimate us that this much sound and frequency can affect your hearing, like that it warns us. Our health is in our hands. Better know about the healthy frequency level and enjoy your movie with a good home theatre effect.
