Understanding TGD-E: Acoustic Compliance for Residential Developments

/in /by

What is TGD-E?

Technical Guidance Document E (TGD-E) sets out the requirements for sound insulation and acoustic performance in buildings in Ireland, supporting Part E of the Building Regulations.

It defines how buildings must be designed and constructed to:

  • Limit sound transmission between dwellings
  • Control impact noise from floors and stairs
  • Manage reverberation in shared internal areas

TGD-E applies primarily to:

  • New residential developments
  • Apartment buildings and multi-unit schemes
  • Material change of use to residential
  • Certain extensions adjoining other dwellings.

For developers, design teams, and contractors, compliance with TGD-E is essential to achieve regulatory approval, avoid costly remedial works, and ensure occupant comfort.

Key Objectives of Part E of the Building Regulations

TGD-E supports two core regulatory requirements:

E1 – Sound Insulation

  • Buildings must achieve reasonable resistance to airborne and impact sound transmission between adjoining dwellings or rooms.
  • Applies to:
    • Walls between dwellings
    • Floors (including separating floors and stairs)
    • Junctions and flanking paths
    • Walls & Floors Between Dwellings and Other Space

E2 – Reverberation Control

  • Internal common areas must be designed to limit reverberation and noise build-up that could affect adjacent dwellings.

The Core Acoustic Requirements

TGD-E focuses on three fundamental acoustic considerations:

1. Airborne Sound Insulation

This relates to noise transmitted through walls and floors, such as:

  • Speech
  • TV or music
  • General living noise

Typical requirements include:

  • ≥ 53 dB DnT,w between dwellings

2. Impact Sound Insulation

Impact noise occurs from physical contact with building elements, such as:

  • Footsteps
  • Dropped objects
  • Furniture movement

Typical requirements include:

  • ≤ 58 dB L’nT,w for floors

3. Reverberation in Common Areas

Common areas such as:

  • Corridors
  • Stairwells
  • Entrance lobbies

must be designed to reduce echo and noise build-up through acoustic absorption treatments.

Structure of TGD-E (Understanding the Sections)

TGD-E is divided into clear sections that guide compliance from design through to completion:

Section 0 – General Guidance

  • Definitions and scope
  • Sound transmission mechanisms:
    • Direct transmission
    • Flanking transmission
  • Design considerations (layout, services, junctions)

Section 1 – Performance Requirements

  • Sets minimum acoustic targets
  • Defines compliance routes:
    • Robust construction details
    • On-site testing

Section 2 – Testing and Verification

  • Mandatory pre-completion sound testing
  • Specifies:
    • Number of tests required
    • Testing standards (EN ISO methods)
    • Reporting procedures
  • Includes provisions for:
    • Failed tests
    • Remedial action

Section 3 – Separating Walls

  • Acceptable wall constructions:
    • Masonry
    • Cavity walls
    • Timber frame systems
  • Key considerations:
    • Mass and density
    • Junction detailing
    • Flanking control

Section 4 – Separating Floors

  • Floor construction types:
    • Concrete floors
    • Timber floors
  • Includes:
    • Impact sound control
    • Floor finishes and overlays
    • Ceiling treatments

Additional Technical Elements

  • Flanking transmission control (critical compliance risk)
  • Construction detailing and workmanship
  • Approved or “deemed-to-satisfy” solutions

Testing Requirements under TGD-E

All applicable residential developments must demonstrate compliance through:

  • On-site acoustic testing prior to completion
  • Testing of:
    • Airborne sound insulation
    • Impact sound insulation
  • Representative sample testing across units

Why TGD-E Compliance Matters

Failure to properly address TGD-E can result in:

  • Failed acoustic tests
  • Delays in project completion and sign-off
  • Costly remedial works
  • Poor occupant experience

Conversely, good acoustic design delivers:

  • High-quality living environments
  • Reduced complaint risk
  • Increased asset value and marketability

Wave Dynamics Approach to TGD-E Compliance

Wave Dynamics are highly experienced in delivering TGD-E compliant projects. Our consultants have delivered more than 60,000 residential units since 2015 when the regulations came in. Wave Dynamics have extensive experience in Value Engineering in residential having worked with our clients on VE to acheive the acoustic targets for our projects as cost efficient as possible.

At Wave Dynamics, we integrate TGD-E requirements into every stage of project delivery:

Design Stage

  • Acoustic strategy aligned with TGD-E
  • Junction and flanking risk assessments
  • Coordination with architectural and M&E design
  • Facade Acoustics.

Construction Stage

  • Site inspections and compliance audits
  • Contractor guidance on detailing
  • Early identification of acoustic risks

Pre-Completion

  • Independent acoustic testing
  • Troubleshooting and remedial strategy if required
  • Clear, defensible compliance reporting

Future Trends in Acoustic Compliance

While TGD-E sets the minimum standard, projects are increasingly targeting:

  • Enhanced acoustic performance beyond compliance
  • Alignment with:
    • BS 8233
    • BREEAM, LEED and WELL
    • HPI (Home Performance Index)

This reflects growing expectations around wellbeing, ESG performance, and building quality.

Conclusion

Technical Guidance Document E is the cornerstone of acoustic compliance in Ireland, ensuring that residential buildings provide a reasonable standard of sound insulation and internal acoustic comfort.

However, achieving compliance goes far beyond meeting minimum values — it requires:

  • Thoughtful design
  • Robust detailing
  • Quality construction
  • Expert testing and verification

Wave Dynamics provides end-to-end acoustic consultancy to ensure your project achieves compliance efficiently, avoids risk, and delivers a high-quality acoustic environment.

Enhancing Learning Environments: The Power of Good Acoustics in Schools

/in /by

In the pursuit of providing students with optimal learning environments, it is essential to recognise the profound impact that acoustics can have on educational settings. Research has consistently shown that good acoustics in schools significantly enhance students’ learning experiences, fostering better concentration, comprehension, and overall academic performance. In this blog post, we will delve into the benefits of good acoustics in schools, backed by research, and explore how the services of Wave Dynamics can ensure the best acoustic outcomes for school projects.

Acoustics in schools play a crucial role in creating an optimal learning environment for students. School acoustics standards include  SDG 02-05-03 – Acoustic Performance in New Primary & Post Primary School Buildings  is the appropriate standard in Ireland, in the UK BB 93 BB93: Acoustic design of schools – performance standards is the defacto standard.  Guidance is also provided on the design of school acoustics through the Institute of Acoustics (IOA) Acoustics of Schools: a design guide.

Here are a few reasons why acoustics are important, along with some research examples that support these claims:

1. Speech Intelligibility: Good acoustics ensure that students can hear and understand speech clearly, which is essential for effective communication and learning. Excessive noise, such as HVAC systems, outdoor sounds, or reverberation, can significantly hinder speech perception and comprehension. Researchers suggest implementing sound-absorbing materials. The quality and delivery of teacher speech have a significant impact on student understanding. Studies have shown that teachers who adopt clear, articulate speech patterns with appropriate pacing and emphasis enhance speech intelligibility for students. Student-related factors affecting speech intelligibility. For instance, studies have shown that children with hearing impairments or language disorders may face additional challenges in understanding speech in noisy environments. Implementing assistive listening devices and offering personalised support can significantly improve speech intelligibility for these students. Furthermore, fostering inclusive classroom practices that promote peer-to-peer communication and cooperation enhances speech comprehension among all students. A study conducted by Shield and Dockrell (2004) found that poor classroom acoustics can significantly impact speech intelligibility, leading to reduced academic performance and increased teacher vocal strain.

2. Academic Performance: Several studies have demonstrated a link between classroom acoustics and academic performance. For instance, a study by Crandell, Smaldino, & Flexer (2005) revealed that improved classroom acoustics, including reduced background noise and reverberation times, were associated with better reading comprehension and higher scores on standardised tests.

3. Attention and Concentration: Proper acoustics contribute to a quieter and less distracting learning environment, enabling students to concentrate better. A research study by Klatte, Lachmann, and Meis (2010) showed that high ambient noise levels negatively impacted students’ attention and performance on cognitive tasks.

4. Special Education and Learning Disabilities: Acoustic considerations are particularly critical for students with special education needs or learning disabilities. Research by Crandell, Smaldino, & Flexer (2005) demonstrated that children with hearing loss or auditory processing disorders faced even more significant challenges in classrooms with poor acoustics, leading to difficulties in speech perception and academic achievement.

5. Teacher-Student Communication: Effective communication between teachers and students is vital for learning. Poor classroom acoustics can strain teacher vocal cords and impede communication. A study by Bradley and Sato (2008) found that teachers in classrooms with good acoustics experienced less vocal fatigue and were better able to maintain vocal quality throughout the day.

It is clear from the research the importance of acoustics in schools and the impact they have on various aspects of education, including speech intelligibility, academic performance, attention, and teacher-student communication. Improving classroom acoustics can create an environment that supports optimal learning outcomes for students.

The Impact of Electric Vehicles on Noise Levels in Urban Centre’s

/in /by

What effect will the growth of Electric Vehicles have on noise levels in Urban Centres? Our Director Sean Rocks discusses:

As electric vehicles (EVs) gain popularity as a more environmentally friendly mode of transportation, questions have been raised about the impact their growing numbers may have on urban noise levels. Based on existing research road traffic noise is generally considered the most annoying type of environmental noise. While it is widely accepted that EVs are quieter than internal combustion engine vehicles (ICEVs), their impact on urban noise levels is still a matter of ongoing research.

In general, EVs are commonly expected to contribute less to urban noise pollution than traditional ICEVs. This is because electric motors generate less noise than internal combustion engines. In fact, many EV manufacturers have designed their vehicles to be nearly silent during operation, in order to enhance the driving experience for their customers.

However, while the engine noise of EVs is quieter than traditional vehicles, EVs are not completely silent. EVs still produce some noise while in operation, including the sound of the tires on the road and the whirring of the electric motor. In addition, some researchers have raised concerns that the near-silence of EVs could create new noise-related hazards for pedestrians and cyclists, who may not hear an EV approaching and may be at greater risk of accidents as a result.

Despite these concerns, research suggests that the overall impact of EVs on urban noise levels is likely to be positive, albeit small. One study published in the Journal of the Acoustical Society of America found that the introduction of EVs could lead to a reduction in urban noise levels of up to 3 decibels (dB) in some areas. This may not sound like a significant reduction, but even small decreases in noise levels can have a big impact on public health and quality of life.

Despite this welcome decrease in noise levels, this will only be achievable after a large percentage of current vehicles are made up of EVs. Therefore as EV growth gradually increases, urban noise levels will slowly decrease. Due to the slow nature of the expected decrease, the change in noise levels are unlikely to be noticed over short increments.

In conclusion, the growth of electric vehicles is expected to have a minor positive impact on urban noise levels, as they are generally quieter than traditional vehicles and will eventually replace a large portion of the current fleet of ICEVs. However, the noise impact will be slow and gradual as EVs grow into a larger share of the current fleet. The health and safety aspects for pedestrians, especially those with vision and hearing difficulties may pose a new risk.
