The Rise of Voice Control

Voice control for the smart home skyrocketed after Amazon released its first-generation Echo smart speaker in 2014. Two years later, Google followed suit with its release of the Google Home smart speaker, as did Josh.ai with its (albeit higher-end) Josh Micro smart speaker. Of the biggest players in voice control, Apple trailed in last with its HomePod smart speaker in 2018.

Out of the gate, smart speakers could do a lot. Looking specifically at DIY smart speakers like the Amazon Echo and Google Home, they could stream music, set alarms and reminders, answer trivial questions, and more. It didn’t take long for manufacturers to build solutions that would also enable these speakers to be used for sending voice commands to smart home devices.

Voice Control + Home Automation

Control4, a leader in home automation systems, noticed the rising popularity of using voice commands to control smart home devices and officially announced its integration with Amazon Alexa in 2016. Today, Control4 smart homes integrate with all the big players in voice assistant technology!

Something magical happens when you pair voice control with a home automation system like Control4. Not only can you control individual devices in your Park City, UT home, like a door lock or TV, but you can also control multiple devices at once using a single verbal command.

For example, when you get home from work, tell your smart speaker to activate your Evening scene. In seconds, the lights change, the shades lower, the temperature adjusts, and your favorite music plays overhead. Control4 paired with voice control lets you enjoy the power of automation—hands-free.

Acoustic Panel Placement

The first element in acoustic treatment is taming reflections. The goal is to subdue reflections, absorbing just enough reverberation so that the sound is natural and presents precisely what the artist and sound engineer intended. Acoustic panels come in different noise reduction ratings, called NRC (Noise Reduction Coefficient). A panel with an NRC rating of .50 means that it absorbs 50% of the sound waves that hit it and reflects the other 50% back into the room.

Acoustic panels should be used at the reflection points of your speakers. For front stage speakers, depending on how they’re aimed, these points could be on parts of the back and side walls. In non-rectangular rooms, other walls may be reflection points, too. Some reflectivity will depend on the types of speakers in your theater, as some are more directional than others.

With a full Dolby Atmos surround system, you have many sets of speakers that are reflecting sound. However, acoustic panels and other treatments are just one part of the sound equation. The seating, flooring, wall coverings, and other furnishings also serve to absorb sound. A professional home theater designer (like Show & Tell AV) understands how furnishings, décor, speakers, and material choices will affect the sound and can recommend the right acoustic treatment strategy for the space.

While there’s no one way to treat a room – each will be different – you can count on some general principles. Side walls in a surround setup will see the most sound reflectivity, so panels with higher NRC ratings may be used for them. Alternatively, décor such as curtains or other soft wall coverings can serve as part of the treatment. In back walls, diffuser panels help disperse sound waves as opposed to deadening them. You want your movie soundtracks and music to be dynamic, so you don’t want too much muffling that takes away the liveliness.

Additionally, front walls can usually benefit from acoustic treatment on either side of the screen. If you have an acoustically transparent screen with front stage speakers behind it, panels on the front wall can also help with those reflection points from the rear, side surround, and potentially ceiling speakers.

Acoustic Panels

Acoustic panels are thin, discreet wall panels typically made of foam or wool that are used to absorb sound. Because soundwaves easily bounce off hard surfaces, which can cause unwanted reverberation, acoustic panels help reduce the number of rebounding waves and dampen unwanted echoes.

Acoustic panels can range in density to absorb more sound or less sound, depending on your unique needs. It’s important to find a balance as too much absorbed sound can create a dead space.

Acoustic panels can also blend with your room décor or look like artwork on your walls. While they may be in full view, you and your guests won’t even notice them as acoustic treatments.

Diffuser Panels

Like we mentioned earlier, absorbing too much sound creates an eerily quiet space, which can be just as bad as having too many echoes. Diffuser panels help reduce soundwaves from causing piercing echoes without fully absorbing sound so that you still experience an open and natural soundstage.

Diffuser panels are typically made of wood and are three-dimensional, with pieces that stick out at varying lengths. When soundwaves hit these panels, they disperse and return to your ears at different intervals so that you’re not “slapped” with sound all at once. The result is a better sense of spaciousness in your home theater or listening room.

What Are Room Acoustics?

Simply put, room acoustics describes how sound behaves within a space. Think of how your speech would sound in an empty room with bare walls and tile floors versus a carpeted room with plush furniture and heavy window drapes: piercingly echoey in the first and soft and quiet in the second.

Because the sound that comes from your speakers is a mixture of direct and reflected sound, the surfaces and objects that make up the theater or listening room in your Salt Lake City, UT home can significantly impact how you hear sound in the room—no matter how great your speakers are. If uncontrolled, reflected sound can distort your audio experience.

Problems Caused by Untreated Rooms

If your room hasn’t been designed with sound in mind, perhaps you’ve experienced these problems:

• Harsh high frequencies
• Muddy bass
• Collapsed soundstage
• Poor speech intelligibility
• Imbalanced sound

Even if you can’t put your finger on any outstanding sound issues in your home theater or listening room, you may be settling for an otherwise lackluster auditory experience that could be immensely improved with an acoustic treatment installation.

Whole-Home Audio

What do we mean by whole-home audio? With audio, it means being able to call up virtually any audio or music you want to enjoy in any room or area of your home with consummate ease and control. If you’re ever frustrated by multiple remote controls, inputs, and different audio settings across your house, you might like this concept. Whole-home audio gives you one consistent way to access all your music and sound sources. Pick a music streaming service and artist, album, radio station, or playlist, and pick the rooms you want to play it. Adjust the volume as desired in each area. Mute an area to take a call. Or have each part of your family enjoy what they want in different areas. Let the kids rock out in the game room while you enjoy Norah Jones in the living room.

How is all that magic done? It starts with a powerful Control4 controller like the EA-5 or CA-10. This is the brain that can control your smart home but also has built-in media distribution capabilities. It can route high-resolution music to all parts of your home and has native support for popular streaming services like Pandora, Tidal, and Spotify. If you have your own digital music library on a hard drive, you can access it through the built-in music server, too. Additional inputs let you listen to other sources like a CD player or turntable, or even sound from a TV. For control, you can use the excellent Neeo remote, a Control4 Touchscreen, a smartphone app, and even a wall-mounted keypad.

Smarter, Simpler Automation

Once upon a time, powerful whole-home automation systems had to be programmed for everything. If you wanted saved automation for watching TV, you might have a scene that lowered the shades, dimmed the lights, started the AV system, and set the temperature to a preferred setting. If you wanted to change that, you’d have to call an integrator like us! However, Control4's When >> Then personalization puts the power of sophisticated programming in your hands, with no technical skill needed. Want to kick off a sequence of things when your garage door opens as you arrive? Turn off the security alarm and cameras, turn on the hallway lights and kitchen lights, start a soothing music playlist, and have the garage door close automatically after 5 minutes. Need to fine-tune the sequence? Do it yourself on your laptop; it's that easy but oh so powerful.

Whole-Home Security

When you have one integrated control point for lights, window treatments, climate, AV, and security cameras, every smart asset in your home can participate in keeping it safe. For example, Control4 systems have a feature called Mockupancy, which simulates your activity within your house to give the illusion that your home is occupied while you’re away. Your Control4 system can manipulate lights, sound systems, TV, and motorized window treatments in a randomized yet natural pattern that will keep anyone casing your property guessing. If someone does intrude, your home can go into action. If a smart camera detects motion around one of your entries, all the lights can go on, you can sound a warning that the intruder is being recorded, and an ear-piercing alarm can go off. Your system can inform you too, and you can have the option of calling the authorities.
