Applications of sound wave technology
One of the advantages of sound is that it can travel to such places where light and sight cannot reach. Industries are using sound for decades as medicine where ultrasound is used to observe internal body organs in the medical imaging. Nowadays smartphones drive the functions in our life, which has created the need for effective and seamless data communication between mobiles and surrounding. One of the best solutions to meet the demand that cannot be fulfilled by Bluetooth, NFC or QR codes is audio data technology. In this technology, data is transferred between the two devices using sound through the devices' speaker and microphone. This makes the process more simple and frictionless. The industry of oil and gas was the first industry which use sound waves in seismic imaging to make 3d images of the earth interior for oil and gas exploration. Now many industries are introducing sound for its incredible ability in transferring data. Following are some of them:
Payments and Finance: Data over sound create a secure connection for authentication between the merchant and customers' phone. Sound is used to facilitate secure transactions between phone to phone or PoS (Point of Sale) to phone. The transaction occurs using data sent over ultrasonic frequencies to establish a connection and identify the payer and payee.
Proximity marketing: Marketing needs the right information in the right time. Nowadays customers prefer purchasing from an in-store visit when they receive in-store offers. The speakers in the store are used to provide promotions, product information, and in-store experiences. The devices are able to deliver data and other value-added services to the users' phone without the need of any additional hardware.
Travel and Ticketing: In the ticketing procedure a QR code is used to scan only one by one. The result leads to inconvenience and slow process. Mass transit venues as airports experience the inefficiencies. Sound ticketing solution mitigates the disorganization because there no need of additional hardware and tickets and people can authenticate tickets simultaneously.
Food market: A restaurant can recognize as a customer walks in and delivers the customer a seamless experience that includes automatic eat and go using data over the sound. The customers register for auto eat and go with a payment. The restaurant app fetches data and authenticates the presence of the customer and complete the transaction.
Submarine communication: The process of underwater communication cannot use the electromagnetic waves beyond a few meters. Sound is ideal for underwater communication for submarines and underwater robotics as it can travel further in the water.
