For many people, interior noise is one of the most important factors in choosing a car and has promoted the world’s automotive engineers to develop many noise-deadening materials and techniques in a seemingly relentless pursuit to deliver a vault-like driving experience.
A car’s mechanical bits, the wind and its tires are the three main culprits of cabin noises. If the engine, suspension, and exhaust are working as intended, then you can bet most of the noises come from either the wind or the tires. The easiest way to reduce any noise is with sound-deadening.
The average car already comes with some in strategic places, but there is always areas that can be improved. The most common and simple sound-deadening techniques include filling up body cavities with acoustic foam and gluing tar-like acoustic materials to the inside of vehicle doors. Undercoating also provides a measure of noise protection.
The quest of the world’s prominent automakers to cut down on cabin noise to the lowest levels possible has resulted in a number of innovative new techniques, most notably Active Noise Cancellation (ANC). Active Noise Cancellation is actually not a new concept, but its only recently that its application has become widespread in the automotive industry.
Essentially the same technology behind the Noise Cancelling Headsets sold by BOSE and others — have you ever tuned out a talkative office-mate with your headsets? — ANC cancel out the engine’s noise while you’re driving!
The system uses small microphones installed in key places in the car to pick up unwanted noises and then develops counteracting signals emitted via the car’s audio system to cancel them out. You’re basically removing bad noise with good noise.
In many luxury cars, the result is an eerily-quiet interior that allows music and other audio sources to be enjoyed in the highest fidelity possible. In fact, the gearheads at , a full-service car dealership in Hurst, TX, tell us that ANC is increasingly becoming a must-have in the premium car segment.
You might be surprised to know that in an increasing number of sports cars and sedans, Active Noise Cancellation is sometimes fine-tuned to let in little more exhaust noise. I mean, would you want a car with some performance cred to be dead quiet? Probably not.
As impressive as Active Noise Cancellation is on its own, it’s only when working together with other noise cancellation technology that auto engineers can achieve a truly quiet interior. Buick, for instance, combines ANC with other traditional techniques to form what it calls QuietTuning™ (check out the new Buick LaCrosse), a package that employs high tech sound dampening materials, acoustically laminated windshields, 5mm thick side windows, and several sound frequencies throughout the car’s interior. Even the tires are specifically chosen to minimize cabin noise.
Active Noise Cancellation is impressive and will surely pave a way for newer innovations that will make future car interior quieter than any of us have ever imagined. We can’t wait to see what the automotive industry has in store.
2020 Corvette C8 Has Most Powerful Bose Sound System Ever
An unforgettable audio experience is likely part of the new Corvette C8 Stingray’s incredible value proposition.
Audiophiles are in for a treat with the 2020 Corvette C8, and that’s because it is available with the loudest, most powerful car audio system Bose has ever put in a two-seat sports car.
The optional Bose Performance system features a whopping 14 speakers, the most speakers the audio company has ever put into a two-seat car. It includes 1-inch tweeters in each upper door panel, 2.5- and 3.25-inch ‘twiddlers’, 4.0-inch midrange drivers, and a 10-inch subwoofer situated in each door.
In addition to pumping out sound with extreme fever, the system also comes with microphones built into the cabin that reduce the effects of external sound, including those from the Corvette’s throaty V8 engine, which sits right behind the driver.
“From the beginning, we knew we had to have an audio system that carefully balanced the need to isolate the occupants from the engine compartment in the rear, while providing live performance-like audio clarity,” said Corvette executive chief engineer Tadge Juechter. “The Bose system technology in the 2020 Chevrolet Corvette Stingray delivers that careful balance.”
Bose has been the official audio partner of Chevrolet since the fourth-generation of the Corvette, which debuted in 1984 with a much more modest sound system than the 14-speaker package of the C8 Corvette.

8 Of The Best ‘Old’ And New Car Features Of 2019
The future in auto tech is already here, and it’s very exciting.
As cars become safer, more fuel-efficient, and more comfortable, it’s harder and harder for the average motorist to imagine how they can be even better. However, for car manufacturers, there seems to be endless possibilities everywhere.
Be it improvements in autonomous tech, electric drivetrains and heads up displays, or upping a car’s luxury, the automotive industry is bringing us many exciting things. Here are eight of the best ‘old’ and new car features of 2019.
1. Blind Spot Sensors
Many of the features in cars focus on driving safety. Blind spot sensors detect when cars are out of the typical range of mirrors and alert you of their presence. This doesn’t remove the importance of taking a quick glance over your shoulder before changing lanes, but it will definitely help reduce the number of accidents caused by blind spots.
2. Phone Starter
Imagine a blistering cold morning, One where the ground is covered by snow and you’re frantically scraping your windshield clean of ice while you bitterly await the car’s heater to put out its end of the bargain. Well, situations like this are a problem of the past as of 2019.
New vehicles can connect to your wireless device and power on remotely, allowing to take on the cold winter months with confidence knowing you will have a heated car waiting for you. In addition to the climate control system, your car’s door locks, alarm, interior and exterior lighting, and liftgate or trunk can also be operated remotely.
3. Heads Up Display
Touch screen menus now have a second cousin. Heads up displays (HUD, for short) are the hip new feature in today’s cars. They are usually in the form of a small display on the front windshield above the steering wheel and below your eyes’ normal field of vision that shows speed, gas levels, and even directions to minimize any reason for you to take your hands of the steering wheel and/or look away from the road.
4. Automatic Parallel Parking
For those of you who have visited small beach towns in Florida or driven through the crowded, narrow streets of San Francisco, you know that parallel parking is a must-have skill. But parallel parking is difficult, and car manufacturers seem to agree, explaining why many 2019 vehicles now come equipped with automatic parking assist systems.
If you’ve been thinking of moving to that bustling Florida town, you can take comfort in knowing there will be a car to handle the tight street parking for you anytime and anywhere, be that car be from a near Coral Springs or a Honda dealer in Seattle.
5. 360 Cameras
You know those rear-end cameras that help with reversing? Those are so 2018. Now you can expect full 360-degree cameras to cover all four sides of your car. This comes in handy in many situations and can prevent unforeseen scratches or .
6. Individual Climate Zones
Thanks to advancements in auto tech, the driver and the passengers can now c inside a of car. By giving each person the power to set his or her own temperature, there will be less bickering over the AC dial.
Many new cars offer dual-zone climate controls for the driver and front passenger, and some can even be equipped with “tri-zone” or “quad-zone” climate control so that rear passengers aren’t left in the cold, so to speak.
7. Pre-Safe Pulse
For those who want to take safety to the next level, the is a new crash safety measure for side impacts. When the car senses an imminent crash about to take place, the driver and passenger seats automatically move closer to the center of the vehicle. For side accidents, even a minimal five-centimeter difference can reduce the impact felt to passengers by one-third.
8. Mirrors with Auto-dim
If you drive a lot at night, you’ve probably noticed that headlights have gotten much more powerful over the years. In some ways, this is tremendously beneficial. Being able to see further and with more clarity is important. However, being on the receiving end of these lights is not only annoying, but it can be dangerous.
Drivers are less inclined to check their mirrors if they get blinded every time they try. For this reason, newer vehicles have equipped mirrors with auto-dimming. These reduce the glare caused by headlights behind you and keep your focus on the road.
Cars Are Getting Smarter
The results of these new features are that cars are getting smarter and drivers now have the tools they need to make better decisions. This combination of factors will surely decrease the number of car accidents and make driving a safer, more efficient and reliable method of transportation.
