Acoustics has always been one of the ways to perceive the world around us. The modern audio system allows not only to enjoy your favorite music, but also to hear it in a new way, distinguishing the smallest nuances of sound. Currently, the audio system for the house is represented by a wide range.
The acoustic system is not a simple commodity, it has always been specific and quite difficult for the townsfolk. Therefore, equipping the house with this equipment requires certain knowledge and a responsible approach when installing. In addition, the relationship of a person's personal space with sound is always an individual decision.
When choosing this equipment, sometimes there is not enough basic price-quality principle. In some cases, there are options for acquiring equipment adapted for specific purposes for a very modest amount of money, or perhaps so that the solution of a simple task will require significant investments.
Classification of musical systems
The possibility of classifying modern audio systems is a relative measure. Tentatively, there are several groups:
- portable systems (mono-structures, including, for example, a player and a tuner);
- stationary systems (including pseudo-modular systems);
- block-modular structures (where each module can be independent and replace).
On the size it can be micro (120-220mm), mini (220-300mm) and midi (300-400mm) centers.
Trademarks are widely represented in the audio segment market. Among them there are more eminent brands, for example, SAMSUNG, SONY, YAMAHA, PIONEER, LG, PANASONIC and less known.
It is also customary to distinguish a separate type of acoustics, called Life Style, the distinctive features of which are unusual design and excellent quality. Here you can answer such brands as JVC and BOSE.
Selecting an audio system
To buy high-quality equipment is not currently a problem. In the market of acoustic equipment are presented various options, the price of which varies depending on various parameters and components. In the middle price category, negative feedback is usually due to limited functionality, for example, the inability to connect wirelessly. Also there may be criticism about the quality of the assembly, although even relatively inexpensive built-in equipment, as a rule, is manufactured in good quality.
There are a number of companies specializing in audio segment products that produce almost perfect acoustics with good sound quality, functionality and ergonomic elements of the system. At the same time, the design is also aesthetically designed.
Despite the fact that manufacturers are actively promoting compact audio systems, the size of the speakers and the quality of the case still play an important role. That is, a small-sized sound source will not be able to draw low frequencies. Thus, quality home equipment should have at least average parameters and a housing that can provide optimal acoustics. This condition, in turn, provides material for the manufacture of the case.
Wood in this case will be preferable to everything, as it will provide high-quality sound and low-frequency processing. Also a good option from MDF, of course, is not without a definite compromise on the quality of the system's operation.
It is generally accepted that it is almost impossible to determine the quality of sound on an amateur level. In view of this, home audio systems are selected not from the point of view of sound criteria, but by external parameters: dimensions and aesthetic appearance. But this approach is not always optimal, because modern technologies have developed to such a level that they can achieve high purity and depth of sound reproduction. And these characteristics become fundamental. Therefore, if you are not satisfied with the standard sound background in the house, but want to really enjoy the music, you need to thoroughly study this equipment and accurately calculate its performance parameters.
Choosing a stereo for a hi-end and hi-fi house is not easy, but if you turn to professionals or carefully study the information on the Internet, you can choose the built-in equipment that is right for your room, depending on its size and individual characteristics.
It is also very important to properly configure the system, to reconcile all components and to implement their quality installation.
Basic sound parameters
The main performance indicators in general terms characterize the operation of any audio system.
- The sensitivity of the speakers. In fact, this is the sound pressure parameter, which is formed by the system. When used at home, an acceptable sensitivity level should be 90 dB or more.
- Frequency range. This characteristic serves as the main, it will depend on the frequency band of waves that can reproduce the audio system. It is worth noting that good audio systems tend to more accurately match the range, identical to the perception of the human ear. Therefore, it is recommended to buy options with indicators in the range of 18-20 000 Hz.
- Sound strips (numerical indicator). This is the number of satellites (speakers) that work at different frequencies. The optimal configuration is considered to be 5.1.
- Power. This parameter is directly proportional to the volume level (the higher it is, the louder the sound). But it is worth considering that this limit should at least 30% exceed the capabilities of the amplifier. The average power for home audio systems is considered to be 50 watts.
The main advantages of built-in home acoustics is that it is capable of providing the best sound quality.
Portable audio system does not have this advantage, since its entire design is more oriented to mobility than to high-quality music playback. In addition, the very place of operation of this device, as a rule, is not profitable in terms of sound quality.
Audio system in the interior of the house
Proper attention in choosing this equipment should be given to its design and location in the interior. The appearance of the main components (amplifier, player, equalizer) is quite typical: it is usually a plastic or metal box of silver or black with a variety of functional accessories.
But as far as the appearance of acoustic systems is concerned, various designs, shapes and colors can be presented here. It can be both miniature objects, and massive.
But immediately it is necessary to focus not on the appearance, but on the technical components and the quality of the system. At the same time, it should be borne in mind that all interior items will participate in the distribution of sound. After all, the same system under different conditions will sound completely different. This feature is primarily associated with the acoustic features of a particular room, its sound-absorbing properties.
Thus, the room where it is intended to install the embedded equipment, it is necessary, if possible, to clean out external noise sources, which may interfere with pure sound. As an option, you can use double-glazed windows, ventilation and split-systems. If necessary, you can wall the walls with special soundproof panels, for example, Ecophon Acusto.
The point is that the sound wave, in accordance with the laws of physics, encountering an obstacle, will dissipate and partially be absorbed. In this case, the denser the wall, the more it reflects the acoustic energy. After all, a lot of reflections cause an echo and level the sound, making it booming. But with too much absorption (an abundance of carpets, furniture, textiles), the sound can become dull and deaf.
You can independently monitor yourself in a simple way, clapping your hands. If you hear distinct sounds or echoes, you will need to mute the sound. And with a deaf sound, on the contrary, it is recommended to maximally free the room from heavy textiles and excess furniture.
One of the best ways to balance the reflections is to dissipate the sound wave. As the scattering surfaces can be book racks, window blinds, paintings.
Interior items of small size provide a reflection effect for 1000 Hz frequencies, for 200-500 Hz frequencies will require surfaces the size of one to two meters.
Good results ensure the imposition of small objects on larger ones. In this case, the sound wave will be scattered more evenly and with a larger frequency range.
Another reason for the problematic sound may not be the correct placement of the speakers.
Modern audio systems
At present, modern technologies have developed to such a level that they allow producing high-quality acoustics with a variety of variations in size and design. The main thing here is to observe all the necessary parameters, for example, the purchase of equipment corresponding to the room, the location of the acoustics and its competent tuning. The room intended for installation of the built-in equipment should be carefully prepared, isolated from noise sources.
Proper reproduction and distribution of different-frequency sounds, as well as synchronous operation of the speakers with a proper tone setting, will help create a high-quality natural sound, and the necessary level of music perception will be attainable.
