Acoustics has always been one of the ways to perceive the world around us. 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 home audio system is represented by a wide range.
Acoustic system is not a simple product, it has always been specific and difficult enough for ordinary people. Therefore, equipping a house with this equipment requires certain knowledge and a responsible approach to installation. In addition, the relationship of a person's personal space with sound is always an individual decision.
When choosing this equipment, sometimes the base price principle is not enough. In some cases, there are options for acquiring hardware adapted for specific purposes for very modest money, and it may be that solving a simple task will require significant investments.
Classification of music systems
The ability to classify modern audio systems is a relative measure. Approximately several groups can be distinguished:
- portable systems (monoconstructions, including, for example, a turntable and a tuner);
- stationary systems (including pseudomodular);
- block-modular constructions (where each module can be independent and replaceable).
In terms of size, these can be micro (120-220mm), mini (220-300mm) and midi (300-400mm) centers.
Trademarks are widely represented in the audio segment market. Among them are more famous brands, for example, SAMSUNG, SONY, YAMAHA, PIONEER, LG, PANASONIC and less well-known.
It is also customary to single out a separate kind of acoustics, called Life Style, the distinctive features of which are unusual design and excellent quality. Here you can answer brands such as JVC and BOSE.
Purchasing quality equipment is currently not a problem. On the market of acoustic equipment are various options, the price of which varies depending on the various parameters and components. In the middle price category, negative reviews are usually due to limited functionality, for example, the inability to connect wirelessly. There may also be complaints about the build quality, although even relatively inexpensive embedded equipment is usually manufactured in good quality.
There are a number of companies specializing in audio segment products that produce virtually flawless acoustics with good sound quality, functionality, and ergonomic system elements. At the same time, the design is also aesthetically thought out.
Despite the fact that manufacturers actively advertise compact audio systems, the size of the speakers and the quality of the case still play an important role. That is, a small sound source cannot pull in low frequencies. Thus, high-quality home equipment should have at least medium parameters and a housing capable of providing optimal acoustics. This condition, in turn, provides the material for the body.
Wood in this case will be most preferable, as it will provide high-quality sound and low frequency processing. Also, the MDF version is not bad in quality, of course, not without a certain compromise on the quality of the system functioning.
It is considered that to determine the sound quality at the amateur level is almost impossible. Because of this, home audio systems are not selected in terms of sound criteria, but by external parameters: dimensions and aesthetic appearance. But this approach is not always optimal, as modern technologies have evolved to a level that allows us to achieve high purity and depth of sound reproduction. And these characteristics are fundamental. Therefore, if you are not content with the standard sound background in the house, but want to truly enjoy the music, you need to thoroughly study this equipment and accurately calculate its operating parameters.
Choosing a stereo for the hi-end and hi-fi categories 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 suits your room depending on its size and individual characteristics.
It is also important to correctly configure the system, to coordinate all the components and to carry out their high-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, it is a sound pressure parameter that is formed by the system. When used at home, an acceptable level of sensitivity should be 90 dB or more.
- Frequency range. This characteristic acts as the main one; the frequency band of waves that the audio system can reproduce will depend on it. It is worth noting that good audio systems tend to more accurately match the range that is 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 bands (numerical value). This is the number of satellites (speakers) that operate at different frequencies. The optimal configuration is 5.1.
- Power. This parameter is directly proportional to the volume level (the higher it is, the louder the sound). But it should be borne in mind that this limit should exceed the capabilities of the amplifier by at least 30%. The average power for home audio systems is considered to be 50 watts.
The main advantages of embedded home acoustics are that it can provide the best sound quality.
A portable audio system does not have this advantage, since its entire structure is focused more on mobility than on high-quality music playback. In addition, the very place of operation of this device, as a rule, is not beneficial in terms of sound quality.
Audio system in the interior of the house
Due attention when choosing this equipment should be paid 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 in silver or black with a variety of functional accessories.
But as for the appearance of the speaker systems, various design options, shapes and colors can be presented here. It can be both miniature items and massive ones.
But right away you should focus not on the appearance, but on the technical components and quality of the system. It should be borne in mind that all interior items will be involved in the distribution of sound. After all, the same system in 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 supposed to install embedded equipment should be cleaned, if possible, from external noise sources that may interfere with clear sound. Alternatively, you can use double-glazed windows, ventilation and split systems. If necessary, you can sheathe the walls with special sound insulation panels, for example, Ecophon Acusto.
The fact is that the sound wave, in accordance with the laws of physics, having encountered an obstacle, will dissipate and partially absorbed. Moreover, the denser the wall, the more it reflects the acoustic energy. Indeed, many reflections cause an echo and level the sound, making it booming. But with too strong absorption (an abundance of carpets, furniture, textiles), the sound can become dull and deaf.
You can make independent monitoring in a fairly simple way, clapping your hands. If you hear distinct sounds or echoes at the same time, it means that you will need to muffle the sound. And with a dull 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 reflections is to disperse a sound wave. As the scattering surfaces can be book racks, window blinds, paintings.
Interior objects of small size provide a reflection effect for 1000 Hz frequencies; for 200-500 Hz frequencies, one or two meter surfaces will be required.
Quite good results are provided by the imposition of small-sized items on larger ones. In this case, the sound wave will be scattered 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
Currently, modern technologies have evolved to such a level that they allow to produce high-quality acoustics with a variety of variations in size and design. The main thing here is to comply with all the necessary parameters, for example, the purchase of equipment corresponding to the room, the location of the acoustics and its intelligent setting. 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 proper tone tuning will help to create high-quality natural sound, and the necessary level of music perception can be achieved.
