Job Title

What is the role? As an Intermediate Noise and Vibration Engineer/Specialist Building Acoustics at LEA, you will analyze, model, and evaluate noise and vibration in buildings and infrastructure projects. You will review architectural and mechanical designs for acoustic performance, perform field measurements, prepare technical reports, and recommend practical mitigation solutions. You will collaborate with multidisciplinary teams, manage multiple projects, and ensure compliance with industry standards, Ontario regulations, and Tarion acoustic requirements, while contributing to highquality, clientfocused engineering solutions. Responsibilities Review architectural, mechanical, and electrical drawings/shop drawings for acoustic integrity (e.g., partition terminations, penetrations sealing, vibration isolation details); provide detailed recommendations and working drawings as needed. Prepare technical analyses using commercial software packages (e.g., Cadna/A, TNM, SoundPlan, STAMSON, INSUL) and proprietary inhouse tools for environmental noise/vibration predictions, impact assessments, mitigation design, and building acoustics evaluations (e.g., partition STC/ASTC/IIC modelling, HVAC/equipment noise propagation, vibration isolation). Complete highquality technical reports with minimal supervision, including baseline assessments, compliance evaluations, mitigation recommendations, Acoustic Design Reviews, Noise Impact Studies (NIS), acoustic specification documents, Vibration Impact Studies, Construction Noise and Vibration Management Plans, and any reporting required to support environmental approvals/permitting, building code compliance, and Tarion warranty processes. Communicate technical findings, potential impacts, and recommended mitigation measures (e.g., partition upgrades, silencer specifications, vibration isolators) clearly to internal teams, clients, regulatory agencies, builders, and stakeholders (e.g., via meetings, presentations, or public consultations). Collaborate closely with project managers, architects, mechanical/electrical engineers, and multidisciplinary teams throughout all phases of project delivery, from initial scoping and proposal development to detail design, construction, and warranty/commissioning. Manage multiple active projects simultaneously, balancing priorities to meet schedules, budgets, and deliverables. Prepare highquality proposals for private clients (e.g., developers, architects) as well as responses to largerscale Requests for Proposal (RFP) and Expressions of Interest (EOI). Stay current with industry standards, software advancements, regulatory changes (including Tarion updates), and best practices to ensure compliance and innovative solutions in building acoustics. Conduct noise and vibration field measurements at industrial, residential, institutional, transportation, and construction sites, including setup, calibration, data collection, processing, interpretation, and specialized building acoustics testing (e.g., ASTC field testing on partitions per ASTM E336, background noise for NC criteria, mockup partition evaluations, and postconstruction commissioning to verify acoustic performance). Participate in professional development opportunities, including training, workshops, seminars, and involvement in professional associations, to maintain and enhance industry knowledge and skills. Support additional assignments within the Transportation & Systems Division. Qualifications Bachelor''s degree (or higher) in Engineering (Acoustical, Mechanical, Civil, Environmental, or related field), Physics, Environmental Science or equivalent. Eligibility for Professional Engineer (P.Eng.) designation in Ontario (or current registration/eligibility with PEO) upon completion of required experience. Minimum of 36 years of relevant consulting experience in environmental noise/vibration and building acoustics assessments (e.g., residential, institutional, mixeduse, shelter/transitional housing developments; transportation, industrial, or construction sectors). Strong demonstrated expertise in building/architectural acoustics, including: Experience in the development and selection of acoustic specifications for sound transmission between spaces (e.g., residential/family units to administrative/common areas), background noise levels, Speech Transmission Index (STI), and speech privacy; Understanding of key criteria from internationally recognised design criteria and guidelines (ANSI, ASTM, ASHRAE, ISO, etc.) and metrics, including STC, ASTC, NIC, NC/PNC/RC, IIC, STI, RT60, etc.; Proficiency in completing Acoustic Design Reviews for partitions, floors, and ceilings (assessing/recommending STC/ASTC/IIC ratings; identifying flanking paths; ensuring compliance with OBC, Tarion Builder Bulletin 19R requirements, and Tarion warranty acoustic performance standards); Familiarity with the fundamentals of indoor HVAC and mechanical/electrical noise prediction and attenuation (airborne, ductborne, and structureborne transmission; NC/RC/PNC criteria; vibration isolation for equipment such as elevators, pumps, boilers, chillers, and rooftop units); and Room acoustics modelling and treatment (e.g., RT60, acoustic absorption and silencing) Strong clientfacing skills, with the ability to collaborate effectively across multidisciplinary teams (architects, mechanical/electrical engineers, developers) to develop practical, projectspecific acoustic solutions Solid understanding of environmental noise and vibration principles, including: Predictive roadway and railway noise and vibration models (e.g., FTA, STEAM, TNM, ORNAMENT). Fundamental sound and vibration propagation algorithms Proficiency with industrystandard modelling software such as Cadna/A, STAMSON, TNM, INSUL, SoundPLAN, EASE or equivalent tools. Comprehensive knowledge of Ontario environmental legislation and guidelines, including but not limited to the Environmental Protection Act, MECP Noise Pollution Protocol (NPC) Publications (e.g. NPC300), municipal noise bylaws, and the MTO Environmental Guide for Noise. Familiarity with sound level meters (SLMs), dosimeters, noise and vibration monitors, and data acquisition systems (e.g., Brel & Kjr, Sigicom, Larson Davis); handson experience conducting sound level and vibration measurements at both source and receptor locations, including longterm monitoring, attended surveys, compliance with ISO/IEC standards, and field acoustic testing (e.g., ASTC per ASTM E336, NIC, background NC measurements). Strong writing and presentation skills, with proven ability to prepare clear, concise technical reports (e.g., Acoustic Design Reviews, Noise/Vibration Impact Study reports, specification documents) and communicate complex findings to nontechnical audiences Assets (Nice to Have) Programming or scripting skills (e.g., Python, MATLAB) for data processing, automation, or custom acoustic analysis. Experience with advanced signal processing techniques and tools. Familiarity with additional modelling tools for rail transit, international standards (ISO 1996, ANSI), or advanced room acoustics simulation (e.g., EASE, RAPONE II). Handson experience with Tarioncompliant acoustic field testing, certification processes, or warranty investigations in residential/institutional developments. Previous involvement in largescale environmental impact assessments (EIA), transit projects, renewable energy developments, or institutional/healthcare/shelter acoustic designs. Membership in professional organizations (e.g., CAA, INCE, ASA).
