Meet the Deaf Architect Who Designs India's Most Acoustically Thoughtful Spaces
There is a particular irony — and a particular beauty — in the fact that the architect most attentive to the acoustic experience of a building is someone who has never heard one. Sundar Krishnan, a principal architect at a mid-sized practice in Chennai, is profoundly deaf. He experiences buildings entirely through their visual, tactile, spatial, and vibrational qualities. And this complete reliance on non-auditory perception has made him exceptionally sensitive to the acoustic dimensions of design that hearing architects often overlook — because they assume sound will simply take care of itself. Sundar knows it will not. The deaf architect career India he has built is one of the most compelling arguments for ability-first hiring in any professional field.
Sundar, 38, completed his B.Arch from SPA Chennai (School of Planning and Architecture) — the institution required additional coordination for site visits and studio critiques but made the necessary provisions under its existing accessibility policy. He is now the principal architect at a nine-person practice, has designed 23 completed projects including two school buildings, one rehabilitation centre, and a 340-seat community auditorium, and was shortlisted for the IIID (Institute of Indian Interior Designers) Design Excellence Award in 2023. He earns ₹1.2 lakh per month.
Why Deafness Sharpens Architectural Perception
Hearing architects design acoustics by reference — they know what good acoustics sound like, and they refer to standards, materials data, and precedent to achieve them. Sundar designs acoustics by inference — he cannot hear a space, but he can understand sound mathematically and spatially with extraordinary precision, because sound has been an intellectual and technical interest rather than a passive sensory experience for his entire adult life.
"Hearing people take acoustic experience for granted," he explains in a written exchange. "I never have. I have had to understand sound as physics, as geometry, as material property. I know more about room modes, reverberation time, and sound absorption coefficients than most hearing architects I have worked with. Not because I am exceptional — because I was curious about something I couldn't just experience, so I studied it instead."
His auditorium project — a 340-seat community performance space in a satellite town near Chennai — required acoustic design that would make spoken word intelligible for audiences with hearing differences (a specific client requirement, given the space's planned use for educational and therapeutic programming). Sundar's solution: a combination of angled reflector panels, strategic absorptive surfaces, and a speaker array designed for hearing loop integration. The acoustics consultant reviewing the design said it was the most thoughtfully conceived acoustic layout he had seen from an architect without specialist acoustic training.
Site Communication: The Systems Sundar Built
ISL-fluent site supervisor
Sundar employs a site supervisor who is ISL-fluent. This was a hiring criterion from his first project as a principal architect. The supervisor serves as the primary real-time communication link between Sundar and contractors on site — a role that goes beyond interpretation; the supervisor understands Sundar's design intent well enough to answer contractor questions independently when Sundar is not on site. This model — a trusted communication intermediary who is a domain expert, not just a translator — is the single most effective system Sundar has built.
Visual site management
Sundar's site documentation is unusually complete. Every instruction to a contractor is confirmed in writing (WhatsApp photos of site conditions plus written follow-up). His site visit protocol: photograph, annotate in AutoCAD or on printed drawings, share with supervisor before leaving site. This creates a paper trail that resolves disputes, reduces errors, and produces the kind of documentation that every well-run construction project should have — but that hearing-led projects often let slide in favour of verbal instructions that evaporate.
Client meetings
Client meetings run with an ISL interpreter present (for new clients) or, for long-term clients who have learned basic ISL vocabulary, with a combination of sign, lip-reading, written notes, and — increasingly — live captioning via Google Meet for remote meetings. Sundar finds that architectural clients, accustomed to communicating through drawings, models, and visual presentations, adapt to his communication style faster than clients in other professional relationships. "Architecture is already a visual language. My clients are trained to read drawings. Moving some of our conversation into written and visual channels is not a great adjustment for them."
Acoustic design and the deaf perspective
Research published in the Journal of the Acoustical Society of America found that spaces designed with explicit consideration for deaf and hard-of-hearing users — including hearing loop systems, reduced reverberation, and visual alarm systems — were consistently rated as higher quality acoustic environments by hearing users as well. Sundar's design philosophy, which starts from the question "how does this space work for everyone?" rather than "how does it work for the majority?", produces buildings that are acoustically superior across the board.
The Architecture School Experience — and What Needs to Change
Sundar's architecture education was, by his assessment, 70% excellent and 30% unnecessarily hard — not because of the work, but because of institutional failures to think about accessibility. Studio critiques conducted verbally without ISL interpretation. Site visits without communication support. Final jury presentations that assumed oral delivery. Each of these was workable — Sundar adapted — but each was also unnecessary; the same experience could have been provided in a fully accessible format with minimal institutional effort.
He now consults with SPA Chennai on accessible studio pedagogies — specifically, how to make critique sessions, site visits, and thesis presentations fully accessible to deaf and hard-of-hearing students. His primary recommendations: ISL interpreters for all group critiques, written pre-submission briefs for jury sessions, and site visit communication kits (visual signalling, written communication pads) as standard equipment alongside safety vests and hard hats.
For Deaf Architecture Students and Professionals
- Build your ISL-fluent site team from the start. A site supervisor who signs is worth more than any other single accommodation. Treat this as a hiring criterion, not an afterthought.
- Leverage architecture's visual native language. Drawings, models, render sequences, and annotated photographs are communication tools that work as well for deaf architects as for hearing ones — and are often more precise than verbal instructions on site.
- Study acoustics deeply. Your intellectual engagement with sound as physics rather than experience is a genuine design advantage. Acoustic consulting and building physics knowledge sets you apart in the market.
- Find practices with visual-first communication cultures. Design-led practices that communicate through drawings and models rather than verbal-only discussions are your natural environments. Browse architecture and design firms with ability-inclusive cultures on IMAbled's job board.
"I cannot hear the building I design. But everyone who enters it can feel whether I understood them. Good architecture is always felt before it is heard." — Sundar Krishnan, Principal Architect, Chennai
Frequently Asked Questions
Can a deaf person become a licensed architect in India?
Yes — the Council of Architecture (COA) has no provision barring deaf individuals from registration or practice. B.Arch programmes across India are increasingly accessible. The RPWD Act 2016 requires educational institutions to provide reasonable accommodation. Several deaf architects practise in India today, with all standard architect functions — design, documentation, site supervision, client management — achievable with appropriate communication systems.
How does a deaf architect manage site communication with contractors?
The most effective model is a ISL-fluent site supervisor who serves as both construction manager and communication intermediary. Supplementary tools include written WhatsApp instructions with site photographs, annotated drawings for every contractor instruction, and a visual site management protocol that documents all communication. This approach produces better documentation than most hearing-led sites and reduces dispute risk.
Which architecture schools in India are accessible to deaf students?
SPA Delhi and SPA Chennai, CEPT University Ahmedabad, and Manipal School of Architecture have made the most documented progress on accessibility. All architecture schools are required to provide reasonable accommodation under the RPWD Act 2016. Contact the student welfare office and the architecture department head directly before applying to confirm current accessibility provisions — experiences vary significantly between institutions.
What makes deaf architects particularly effective at acoustic design?
Deaf architects who engage deeply with acoustic design tend to approach it analytically — through physics, mathematics, materials science, and precedent research — rather than relying on intuitive hearing-based assessment. This produces more rigorous, evidence-based acoustic decisions. Their designs also tend to integrate hearing loop systems, visual alarm systems, and reduced-reverberation specifications more naturally, as these are design considerations they engage with from personal experience.
How can architecture firms create more accessible workplace environments for deaf architects?
Key steps include: hiring ISL-fluent support staff or funding ISL training for a team member, running all design critique sessions with written documentation or interpreter support, using visual project management tools (Trello, Asana, annotated PDFs) as the primary communication medium, and ensuring client-facing work (presentations, site meetings) includes communication support. Most of these changes improve clarity and documentation for the entire team. For detailed guidance, visit IMAbled's employer hub.
