Acoustical Design Engineer

MEDIUM DemandLOW AI RiskGROWING in SL· Rs.120k+ /mo

Acoustical Design Engineering applies rigorous physics to the practical problem of making buildings quieter and better-sounding — from specifying floating floor systems in a Colombo apartment tower to designing noise enclosures for a factory. The field is niche in Sri Lanka but growing, and the IOA credential creates genuine overseas career mobility in UK, Australia, and the Gulf. For those who want engineering work with a scientific measurement dimension, this is a distinctive and satisfying specialism.”

About This Role

Analyzing sound propagation and vibration using wave mechanics and numerical simulations.

A Day in the Life

Engineers acoustic solutions into buildings and industrial facilities — calculating noise transmission paths, specifying noise control products, and supervising acoustic performance testing from a structural engineering perspective.

  • Calculate structural noise transmission — impact noise, airborne sound, flanking paths through structure
  • Specify acoustic isolation systems — floating floors, resilient mounts, acoustic gaps
  • Design industrial noise enclosures and barriers for machinery noise control
  • Coordinate with structural engineers on floating slab and acoustic joint details
  • Review contractor shop drawings for acoustic compliance
  • Supervise installation of acoustic products and verify workmanship
  • Perform post-construction acoustic testing to ISO or BS standards

Work Environment

HYBRIDTeam: SMALLBUSINESS CASUALRemote: LOW

Engineering consultancy offices and construction sites. The Acoustical Design Engineer role is more engineering-delivery focused than the consultant variant — with responsibility for acoustic specification compliance during construction. In Sri Lanka, roles typically exist within larger MEP or civil engineering firms, or as part of environmental engineering consultancies.

Typical hours: 48h/week · WLB score 6/10 · OCCASIONAL overtime

Construction project deadlines and site supervision requirements can extend working hours periodically.
