Before we introduced some issues related to the acoustic treatment of home theater decoration: "Old Snail: Talking about the Acoustic Treatment of Home Theater Decoration", this article does not systematically explain, but emphasizes 9 very important issues. I hope that everyone will pay more attention to debugging better home theater sound effects.
Place the speaker
The correct placement of the speakers is the key to good sound reproduction in the room. If you can follow the introduction of the speaker placement in the previous sections of this chapter, it will take a few hours to try to find the proper placement position for the speaker, which will not only achieve good sound reproduction, but also increase the number of sound reproduction effects. Listening to the experience and being able to hear the difference in sound quality. All room acoustics processing is based on the proper placement of the speakers. If the speakers are placed in the wrong position, all the rest of the effort is futile.
2. The length, width and height of the room should have a good proportion
Although in most cases, the room is already built. The ratio of length, width and height has already been fixed. However, if there is a chance to select a room for the listening room, it is best to refer to the ratio of the length, width and height of the room listed in section 3.1 of this chapter in order to avoid standing waves as much as possible. Because this is also a selection condition for the audio equipment to obtain good sound reproduction.
3. Try to avoid bare parallel surfaces
If there are bright, face-to-face parallel surfaces without any acoustic treatment in the room, you will hear multiple breaths. Simply apply a sound absorbing material to one of the surfaces, such as sound absorbing foam, ASC's sound absorbing material that eliminates multiple echoes, a small piece of tapestry or carpet-like sound absorbing material, especially ASC's Tube. Special sound absorbing equipment such as Trap can absorb bass at the same time, allowing the reflected sound waves of the side wall to spread and eliminate multiple echoes.
4. Absorb or scatter reflections from side walls and floors
Try to lay a carpet on the smooth ground before the speaker and the speaker. Place some sound-absorbing or scattering sound waves on the side wall between the speaker and the listening position. Try to avoid reflections such as bare walls and windows near the speakers. surface. American ASC's Tower Trap sound tubes, various sound absorbing foams, and RPG diffuser screens can be effectively used to eliminate side wall reflections. The bookshelves placed on the side of the side wall also spread the sound waves well.
5. Keep the reflector away from the speaker
Audio racks, power amplifiers, furniture, and other objects placed near the speakers can degrade the sound and sound fields. Therefore, you have to try to move these objects away. For example, move to the back of the speaker. If they cannot be removed, they should be covered with sound absorbing materials.
6. Strive for a room with a very high height and a slope
Although it may not be possible, it is best if you can choose a room with a higher height and a slope to make a listening room. Such a room not only changes the indoor resonance mode between the floor and the ceiling, but also reduces the early reflection at the listening position, making the bass more round and round, and the space is more spacious. The speaker should be placed at the lower end of the ceiling.
7. Balance the absorption of treble and bass
Most rooms tend to absorb too much of the treble, while the absorption of the bass is not enough. Carpets, curtains, and soft furniture are used in conjunction with some materials that absorb bass to keep the reverberation time constant throughout the entire frequency band. Overweight and slow bass is caused by the imbalance of reverberation.
8. Move the listening position to achieve the best balance of bass
Standing waves will produce some constant high sound pressure and low sound pressure zones indoors. Try moving the listening position for the best balance. Avoid sitting in the ground near the back wall, because the bass here will be too heavy.
9. Use irregular planes or grotesque objects to disturb the remnant graphics
Deliberately placing some furniture or objects will help to disturb the standing waves formed in the room. Placing large pieces of furniture behind the listening position will spread the reflections of the back walls behind the listener.
I believe that after careful matching and adjustment, you will be able to receive a perfect home theater. If you are interested in home theater, join us, Home Theater Network official WeChat: cnhifi, home theater club (QQ group) 173801483.
What is an outdoor wireless access Point?
Outdoor Wireless Access Points (aps) are wireless networking devices designed to provide Wi-Fi coverage in outdoor environments and are often used in industrial and corporate environments that require outdoor Wi-Fi access, as well as in public Spaces such as parks, stadiums, campuses, and outdoor event venues.
Outdoor wireless access points are built with a variety of weather conditions and tolerance to high temperatures in mind, so they are often equipped with weatherproof enclosures to protect internal components from moisture, dust, and other environmental elements. In addition, outdoor wireless access points are equipped with high-gain antennas that enable long-range coverage while simultaneously supporting multiple devices. Some outdoor wireless access points also have grid networks that connect a large number of wireless access points to provide seamless Wi-Fi coverage over a wide area. To protect the security of the network, outdoor wireless access points are also equipped with advanced security features such as WPA3 encryption and guest access restriction. As an important component of outdoor Wi-Fi infrastructure, outdoor wireless access points provide a reliable and secure connection within a certain range of the external environment.
Why are outdoor wireless access points important?
Here's why:
In order to provide reliable and fast Wi-Fi coverage in outdoor environments, outdoor wireless access points must be equipped to cope with the increasing use of mobile devices and meet the wireless connectivity needs of public places. This will support individuals to stay connected, allowing them to use the Internet in public Spaces such as parks, stadiums and universities.
For many organizations and industries, outdoor Wi-Fi connectivity is essential for daily operations. For inventory management and control systems, wireless facilities and warehouses must use wireless communication. These systems must be supported by wireless access points.
Wireless access points can support new applications such as outdoor video surveillance, smart lighting and environmental monitoring. Without outdoor wireless access points, many applications that require wireless connectivity will be difficult to sustain.
Visitors expect Wi-Fi connectivity in public areas such as parks and stadiums. Businesses that provide outdoor Wi-Fi can significantly enhance guest interaction and improve the overall customer experience.
All in all, outdoor wireless access points are equally important to businesses and companies because they allow them to reach out far beyond their original physical premises, reaching out to potential audiences that would otherwise be out of reach.
What are the important characteristics of outdoor wireless access points?
The following characteristics of an outdoor wireless access point are important:
Weatherproof and durable design: Outdoor wireless access points must be able to withstand harsh weather conditions and extreme temperatures. In addition, a weatherproof case is required to protect internal components from moisture, dust, and other environmental elements.
High-speed connectivity: In order to provide service to a large number of users and devices, outdoor wireless access points should provide high-speed connectivity.
Advanced Features: To provide high performance and powerful support for a wide range of devices, outdoor wireless access points should have advanced features including beamforming, MU-MIMO technology, and grid networking.
