SonaVyx automatically evaluates your measurements against the building codes and regulations that apply to your project, anywhere in the world.
STC 50 minimum between dwelling units (IBC Section 1207)
International Building Code requires STC 50 for walls, floors, and floor-ceiling assemblies separating dwelling units. Field-tested FSTC 45 minimum.
DnT,w varies by country (typically 52-55 dB)
EN 12354 calculation methods with national requirements. Most EU member states require DnT,w of 52 dB or higher between dwellings.
DnT,w + Ctr >= 45 dB airborne, L'nT,w <= 62 dB impact
Approved Document E of Building Regulations. Pre-completion testing required for new-build residential. Robust standard detail alternative available.
R'w >= 53 dB between dwellings (enhanced: 56 dB)
German standard for sound insulation in buildings. Distinguishes minimum requirements from enhanced (SSt III) recommendations. VDI 4100 offers higher comfort levels.
Rw + Ctr >= 50 dB (BCA Class 2-3 buildings)
National Construction Code references AS/NZS 1276 for sound insulation ratings. BCA requires Rw + Ctr >= 50 between sole-occupancy units.
Building acoustics measurement is a critical step in the construction lifecycle. Whether you are an architect verifying that a partition wall meets the specified Sound Transmission Class (STC) rating, a construction manager conducting pre-completion testing under UK Approved Document E, or a building inspector validating compliance with IBC Section 1207 requirements, accurate acoustic measurement is essential. Traditional approaches require specialized equipment costing thousands of dollars — omnidirectional loudspeakers, calibrated microphones, sound level meters, and dedicated software. SonaVyx changes this equation by putting ISO 16283-compliant measurement tools in your pocket.
Sound insulation between rooms is the most commonly tested building acoustic parameter. ISO 16283 Parts 1 through 3 define the field measurement procedures for airborne sound insulation, impact sound insulation, and facade sound insulation respectively. These measurements determine whether the as-built construction meets the design specification and applicable building code. SonaVyx implements the low-frequency procedure of ISO 16283-1 Annex A, critical for accurate assessment of lightweight constructions where room modes dominate below 100 Hz. The platform automatically calculates single-number ratings per ISO 717 — including Rw (and STC), Ln,w (and IIC), and the spectrum adaptation terms C and Ctr that account for different noise spectra such as road traffic or music.
Beyond partition performance, building acoustics encompasses room acoustic quality. The reverberation time (RT60) of a classroom, office, or healthcare facility directly impacts speech intelligibility, occupant comfort, and productivity. SonaVyx guides you through spatially-averaged measurements per ISO 3382-2, capturing multiple source and receiver positions to produce statistically valid results. The platform computes T20, T30, and Early Decay Time (EDT) across octave bands from 125 Hz to 4 kHz, overlaid with target ranges for your specific room type. Clarity indices C50 and C80 quantify the balance between early and late sound energy, directly relevant to speech and music performance in the space.
The most time-consuming part of building acoustics work is often not the measurement itself, but the post-processing and report generation. SonaVyx automates this entirely. After your measurements are complete, the platform generates a professional PDF report that includes measurement setup details (room volumes, surface areas, equipment used), frequency-band data in tabular and graphical form, single-number ratings with uncertainty per ISO 12999-1, and a clear pass/fail verdict against the applicable building code. Reports can be branded with your company logo and customized for your client. This reduces report turnaround from days to minutes, enabling consultants to deliver results on-site during the measurement visit.
Building acoustic requirements vary significantly across jurisdictions. In the United States, IBC Section 1207 mandates STC 50 (or field-tested FSTC 45) between dwelling units. European countries implement EN 12354 with national annexes — Germany (DIN 4109) requires R'w of 53 dB between dwellings with enhanced levels per VDI 4100, while France requires DnT,A of 53 dB between dwellings. The UK mandates pre-completion testing under Approved Document E with DnT,w + Ctr of 45 dB for airborne and L'nT,w of 62 dB for impact. Australia references AS/NZS 1276 with Rw + Ctr of 50 dB between sole-occupancy units. SonaVyx maintains a continuously updated database of these requirements, automatically selecting the correct criteria based on your project location and building type. This eliminates the risk of evaluating measurements against the wrong standard — a surprisingly common and costly mistake in practice.
SonaVyx serves three primary audiences in the building acoustics space. Architects use the platform during design development to verify acoustic performance predictions against actual site conditions, catching issues early when remediation is still feasible and cost-effective. Construction managers rely on SonaVyx for quality assurance during the build phase — testing partitions, floors, and facades as they are completed rather than waiting until the end of the project when failures are exponentially more expensive to fix. Building inspectors and acoustic consultants use SonaVyx for formal compliance testing, generating the documented evidence required for code approval and certification. In all three cases, the smartphone-based approach means acoustic testing can happen on any site visit without advance scheduling of specialized equipment or personnel.
