Aural Exchange sells high quality soundproofing materials, acoustical panels and sound dampening products used in compliance of global building regulations. Run by experienced acoustic consultants, we offer patented knowledge-driven innovations in the field of acoustics and sound absorption. Aural Exchange is a direct online retailer for noise and vibration control, acoustic products and acoustic consulting services in India. Export sales and consulting outside India are handled by our group company Acoustic Tribe (www.acoustictribe.com)
Aural Exchange was founded to solve two fundamental problems in the Indian market.
a) Provide direct access to practical and reliable soundproofing and acoustic products.
b) Address the shortage of qualified acoustic consultants and designers
Unlike the expensive acoustic panels available at this time, our products are not only dramatically less expensive due to our robust supply chain , but also come with significant performance advantages. Today Aural Exchange takes great pride in offering a full line of acoustical products from Vicoustic, Texsa, Ecohush, Roxul, Nankarrow, Knauf, Owens Corning, Echoseal, Senor, BASF, Isover, Chova, Getzner and many other brands based on the “better price/better performance” principle.
Aural Exchange continues to distribute industry-leading solutions that offer incredible performance at a price dramatically less than other over-hyped, much more costly alternatives.
One huge difference between Aural Exchange and our competitors is our passion to help ALL of our customers attain truer sound at a reasonable price. When it was apparent that there was no good, straight-forward guide to help customers build solid, reasonably-priced studios, our founder wrote the acclaimed Knowledgebase.
Over time, we’ve added to our growing staff quite a crew of acoustic engineers who help produce our exceptional, informative – and most importantly, understandable catalogs and websites.
Since our humble beginnings years ago we’ve become known for adding lots of value to your acoustics quest by offering tons of free suggestions and advice. We’ve ultimately evolved this into many thousands of free consultations facilitated by our industry-leading Room Analytics Report. Every one of our acoustic specialists are practicing musicians with considerable recording experience. Our team includes degreed acoustical engineers and THX certified professionals, MI grads, home theater experts, and veterans of many years of acoustical design and installation. They’re all at Aural Exchange because they love good sound!
Whether your space is a home studio, home theater, conference room, church multi-purpose room, professional studio, rehearsal hall, or simply your office, we can help you get the right sound at the right price! We gently help our customers understand why our products offer the best value and performance – and let our customers decide if an Aural Exchange purchase is right for them.
While there are a few other decent acoustical products out there, nowhere else will you find a staff like ours; a staff that’s committed to the excellence of every installation regardless of scope or price. Every day we live and breathe acoustics with a passion for better sound that sometimes borders on the fanatical. With all our years as performing musicians (both on tour and in the studio), as broadcasters, as music lovers, and as professional sound engineers, we know what you’re going through in your quest for better sound.
