Audiometric Testing Rooms
Designing and building an audiometric testing room requires careful attention to a wide range of acoustic and clinical factors. Whether for pure-tone or free-field assessments, QuietStar delivers fully compliant and high-performance testing environments that meet international standards, including ISO 8253.
Designed for Precision. Built for Comfort.
Clinical hearing assessments — from unaided audiometer-based testing to aided hearing aid evaluations — require a carefully controlled acoustic space. Whether the patient is an adult or a child, consistent and accurate results depend on:
Low ambient noise levels
Controlled reverberation times
Defined room layout and speaker positioning
We design spaces that enable clear and repeatable results across all types of audiological testing, in line with ISO 8253-1, 8253-2, and 8253-3 standards.

Key Design Considerations
✅ Room Size
A clinical audiometric testing room should typically be 8–9m², increasing up to 24m² for paediatric assessments or sound field testing. Larger rooms help minimise the acoustic impact of furniture and equipment.
✅ Ambient Noise Control
Ideal background noise levels are outlined in ISO guidance (see Table 1 below). Our rooms are built to meet — or come as close as possible to — these levels, ensuring accurate results down to 0dB HL.
✅ Reverberation Time
To maintain test accuracy, reverberation times should be kept below 0.25 seconds. We achieve this through acoustic wall and ceiling treatments, or purpose-built absorptive structures in new constructions.
✅ Room Layout & Equipment
To avoid interference with measurements, the audiologist, control equipment, and furniture should ideally be located outside the test room. Patients are viewed from a separate, acoustically decoupled observation area.
✅ Loudspeaker Positioning
When free-field speakers are used, they should be installed at head height and at least 1m from the reference point to avoid distortion due to sound dispersion.
Building or Refurbishing a Test Room
🛠 Refurbishment
Existing rooms can be upgraded with acoustic wall linings, secondary glazing, bespoke absorption systems, and acoustic doors and windows to meet testing standards and improve sound isolation.
🧱 New Builds
Our preferred construction method is a room-within-a-room — structurally isolating the test area to minimise sound transmission.
Single acoustic walls can achieve 40–45dB reduction
Double acoustic walls can deliver up to 70–75dB
📍 Location Matters
Avoiding external noise sources like traffic, plant rooms, or busy corridors is ideal. Where that’s not possible, enhanced soundproofing measures are implemented to protect the clinical environment.
Patient & Clinician Comfort
Clinical performance and patient experience go hand-in-hand. Our audiometric rooms are designed not only for acoustic excellence but also for comfort and usability. This includes:
Patient-friendly lighting, colours, and finishes
Minimalist, uncluttered design
Acoustically treated ventilation or silent air conditioning systems for consistent air quality and thermal comfort
These features help reduce anxiety for patients who may already feel disoriented or vulnerable due to hearing loss.
A Collaborative Approach
We work closely with NHS departments, private audiology providers, estates teams, and architects to ensure the final facility meets clinical requirements, user needs, and budget expectations — from initial design to project handover.
