Qualcomm has announced that it will be introducing active noise cancellation or ANC technology onto its newest product platform, CSR8675.
Qualcomm is a San Diego, California-based company. The American multinational is specialized on telecommunication equipment and semiconductors. It markets and designs wireless telecommunications services and products.
Now, it might be the first company to introduce ANC to a SoC. SoCs are system-on-chip systems. Qualcomm will be introducing the active noise cancellation technology to the CSR8675.
As such, it will become the first product of its kind to feature such a technology. The company went to offer some details.
According to Qualcomm, the inclusion eliminates the need of a separate ANC chip. These are usually introduced in headphones. However, the headphone’s such process is more costly and complex.
Active noise cancellation is also known as active noise control. It is a specifically developed method. This helps reduce unwanted noises.
ANC works by adding an additional sound. This second is designed specifically so as to cancel the unwanted, initial disturbance.
More technically, the technology works as follows. The noise-cancellation device or software will release a sound wave. This will have the same amplitude as the original sound. However, it will an antiphase or inverted phase.
The original and secondary sound waves then combine. This process is called interference. In such cases, it a destructive interference, as the two effectively cancel one another.
Such a process helps audio manufacturers deliver better audio experiences. ANC is used so as to offer premium audio, in even smaller designs.
CSR8675 will be the first Qualcomm platform to come with a readily integrated ANC. On its own, it is a Bluetooth audio system SoC.
It sports a Flash platform which is fully integrated into the system. It is also embedded with a 120Mhz 24-bit DSP. CSR8675 supports both the Qualcomm aptX HD and the Qualcomm aptX audio technologies.
These both should ensure a high-quality, consistent Bluetooth-powered audio streaming.
Anthony Murray went to offer some further information. He is the Qualcomm Technologies International, Ltd. General Manager and Senior Vice President.
He pointed out the market’s demand for specific devices. These include stereo wireless in-ear headsets and devices. According to Murray, users no longer want to sacrifice audio quality.
They want to enjoy their audio experience no matter their surrounding environment. Murray stated the first Bluetooth audio SoC with an integrated ANC could open new roads.
More exactly, it could ensure a collaboration between manufacturers and such device developers. Their collaboration would target the creation of a wider range of products. These latter would all have an integrated active noise cancellation technology.
ANC technology is already available in some headsets. Still, these are usually high-end sets and somewhat more inaccessible. New ANC products would target casual headsets. They should also have lower retail price values.
The ANC integrated CSR8675 is already being used. Tom Li, the Fujikon Industrial Co., Ltd. Executive Vice President of the Business Development, went to explain.
According to Li, the company added the said Qualcomm platform to its own products. It has been integrated into its Active Noise Cancelling Bluetooth headphones. As such, these should offer a higher quality audio experience.
Currently, the respective headphones have a reported noise canceling performance coming up to -23dB.
