Bose Moves to Wireless

Bose has recently announced that they would be releasing four new headphones and it is big news for the geeks at Bose is the biggest brand name in the headphone industry and they also sell the most devices compared to other brands. They have also started their research and development in the past 10 years to deliver better sound to their customers. Their full sized QuietComfort flagship headphones have been the leader in the market for the past few years because of excellent music and detailed sound which was unimaginable during the early years of noise cancellation. There are enough reasons why Bose manufactures the best noise cancellation headphones.

Bose has introduced wireless Bluetooth connectivity in the new released models of 2016 top of the line headphones. This would be very helpful for those apple fans who are bound to lose the 3.5 mm jack in the new iPhone according to market rumors.

According to the engineers at Bose, the QuietComfort 35 has updated miniaturized microphone arrays which are inside and outside of the ear cups, thus helping in detecting and removing unwanted noise. The headphone series also has automatic volume optimization EQ curve which has been provided to present best tone and sharp music clarity at any volume. It also has a huge 20 hours of battery life which will make long hour journeys or flight easy. It is available in both black and silver grey color.

The other release which is due in September 2016 would be the company’s first in ear wireless earphones with neckband construction, Quiet comfort 30. The earphones sensors allow the listeners to control how much noise cancellation is required according to the surrounding conditions. If you want to listen to your surroundings, then you have the option to turn off the noise cancellation feature. This would be good if you are in traffic or doing some activity jointly.

You can connect all the new 2016 headphones to the BoseConnect app for more functions. The app will help you in managing more Bluetooth devices by just dragging the device you wish to use and the app will connect it automatically. You can also switch between other devices from one music player to another seamlessly. You can change language, set a timer for automatic off and can give your headphone a personalized name. The app downloads the hardware software and will install it whenever want it to be done. The Bose app works with few products i.e. QC35, Sound sport wireless headphones and SoundLink wireless II.

Seeing the boom in fitness category, Bose announced that they would release two new in ear wireless headphones which will be available in the market in black or aqua blue color. These headphones would be lightweight and one model will be fitted with device which monitors heart rate within each ear bud to give you accurate information just as a chest mounted monitor. They would be called SoundSport and an advanced model called SoundSport rule which will have the heart rate measuring feature. These modes would be resistant to sweat and water. The cable has also been designed in a way to keep the water off. The headphones have a battery life of 6 hours and are price at 149.95$. The pulse version is priced at 199.95 and has a shorter battery life of 5 hours.


Sound Proofing and Absorbing

Difference Between Sound Proofing and Sound Absorbing

What will you do when someone suffering from noise problem could not search for soundproofing on internet? Many people ask me the ways to keep the sound within specific area. In such condition we usually talk about the type of noise and the room to deal with the problem.

Many people ask about the cost of soundproofing panels or foam as they think it can solve their problem. This is a common misconception as foam itself cannot stop the sound. In fact, foam absorbs the sound instead of stopping it.

Audio sounds can be controlled by two types of products- one that stops the sound and the other that absorbs the echo of the sound.

In order to make people understand this entire idea I suggest building an aquarium to put water in it. What will be the best material for it? Suppose they use sponges on the walls to restrain the water but it will absorb it. Similarly the sound in a room behaves like water in the aquarium. The water can be retained in the aquarium unless its walls are made of glass panels with seal as soft materials like sponges can absorb the water. In order to block the water or sound in a space, it has to be made air-tight from heavy and dense materials.

Noise absorbing

Foam from an anechoic chamber to absorb noise

Usually light, soft and fluffy products are used for absorbing the sound in a room to reduce its echo in that area. Suppose, while finishing your basement room you install studs to frame the wall with sheetrock. If you use 2” thick egg crate foam instead of sheetrock then you can clearly hear the sounds spoken from the other side of the foam as it has no or least mass or density.

Noise blocking

The products that do not allow the sound to leave or enter a space are installed while constructing the wall to decouple it and to obstruct the contact of its two surfaces. If, in the above example you use layers of sheetrock on either side of the wall instead of foam, you will not be able to hear the conversation on the other side of the wall.  


While constructing a standard racquetball court in a gym the walls are made two feet thick to produce consistent echo sound when you clap in the room or throw several balls in this room from various directions to bounce on its walls. Now suppose you finish the walls, ceiling and floor of that room with 2”thick foam and throw same number of balls in it to bounce again. You will see that now they do not bounce after hitting any surface because the energy of the balls will be absorbed by the foam insulating the room. Thus it proves that soft foam insulation on all the surfaces can absorb the echo instead of sound.

I am thankful to you if you got the idea I tried to convey about the difference between blocking and absorbing sound clearly through my raw examples, without using any technical thing. Non-technical people can be educated more easily about their noise problem through simple things as they are not going to be acoustic experts.
