Learning has been my passion. I have discerned sounds produced on tabla as part of my doctoral research work completed from the Indian Institute of Technology, Kanpur. In hindsight, being a PhD student was a pursuit that gave me tremendous joy amidst uncertainties. Looking at tabla through different lenses, such as musical, signal processing, vibrational, and psycho-acoustical, has yielded some interesting observations. I continue to expand my inner lenses through which I could look at music, musical instruments, and life holistically. Currently I am offered a position in Media Centre, IITK, to develop a Music Studio.

Organized Workshops

Employees from Hindustan Aeronautical Limited, India, participated in a workshop held at the Acoustics lab, IITK, in February 2023. There were two experiments. [a] Tabla’s Sound Recording: Data Acquisition Using Microphone and Determining its Frequency Spectrum [b]. Tabla Membrane Vibration: Out-of-the-plane displacement measurement using two high-speed cameras. The workshop was conducted for 30 employees for a duration of one month.

Attended Workshops

Participated in Ignaz Kögler Summer Research Camp in Acoustics, on September 27th to 1st October 2021 from Techniche Hoschule, Ingolstadt, Germany.

Awards

Our paper titled “Investigating the asymmetry in tension in a tabla membrane from a musical perspective” fetched the best paper award in the National Symposium on Acoustics (NSA 2023), Odisha, held from 24-26 February, and organized by the Acoustical Society of India and VSSUT Odisha.
