Before you sign the deed or commit capital to a development project, know what the walls actually do. Bixlume conducts calibrated acoustic surveys between apartment units in Argentina — delivering a technical report that compares real measurements against current regulations.

Why It Matters

Developers Promise Quiet. Numbers Confirm It.

Acoustic insulation is one of the most frequently misrepresented features in new apartment developments. Marketing brochures reference standards and certifications — but without independent measurement, there is no way to verify whether those promises hold up in the actual building.

Bixlume conducts field measurements between functional units — between floors, between sidewalls, between a unit and a common corridor — using calibrated instruments and established methodology. The result is a technical document you can act on.

For Buyers

Know what you are purchasing before the transaction is final. Acoustic performance is a property characteristic that affects daily quality of life.

For Investment Groups

Verify that the development meets the specifications it was sold on before committing or distributing capital among co-investors.

For Building Administrations

Establish an objective baseline when residents report noise complaints between units, supporting informed decisions on remediation.

What We Measure

A Complete Acoustic Picture

Each survey covers the acoustic transmission pathways relevant to residential comfort and regulatory compliance in Argentina.

Airborne Sound Insulation

We measure the Weighted Sound Reduction Index (Rw) between adjacent units — walls, floors, and ceilings — to determine how effectively the building envelope attenuates speech, music, and ambient noise from neighboring apartments.

Impact Noise Transmission

Footsteps, furniture movement, and dropped objects generate structure-borne sound. We measure the Weighted Normalized Impact Sound Pressure Level (Ln,w) through floor assemblies to characterize this transmission pathway.

Regulatory Comparison

Measurements are compared against IRAM standards applicable in Argentina, as well as any acoustic specifications stated in the developer's technical documentation or the purchase agreement.

Treatment Recommendations

When measurements fall short of the applicable standard, the report includes a section describing the technical options available to improve acoustic performance — so you know what remediation looks like in practice.

Technical Documentation

Every survey produces a structured written report with raw measurement data, frequency-band breakdowns, the regulatory values being compared, and a clear statement of conformance or non-conformance.

Field Calibration

All instruments are calibrated on-site before and after each measurement session using a certified acoustic calibrator, ensuring the validity of the data collected throughout the survey.

Who Requests This Service

Built for Decision-Makers

Individual Buyers

You are about to sign a deed on a new or recent apartment. The developer's brochure mentions acoustic insulation. You want to know whether the unit you are buying actually meets the described standard before the transaction closes.

Co-Investment Groups

A group of investors is purchasing units in a development or evaluating a finished building for acquisition. An independent acoustic survey provides an objective data point on construction quality as part of technical due diligence.

Building Administrators

Residents in your building are reporting persistent noise between units. You need an objective measurement to understand whether the issue is a construction deficiency or a behavioral matter — and to document the situation formally.

Common Questions

Frequently Asked Questions

The primary reference framework in Argentina is the IRAM 4044 standard, which establishes minimum acoustic insulation requirements between dwelling units. Some provincial and municipal codes incorporate additional requirements. Where a developer has specified acoustic performance values in contractual documentation, those values also form part of the comparison baseline in our reports.

The duration depends on the number of unit pairs being measured and the types of transmission pathways included in the scope. A single unit pair with both airborne and impact noise measurements typically requires a half-day site visit. Larger surveys covering multiple pairs or entire floors require scheduling across multiple sessions to ensure controlled conditions in each measurement position.

For the most accurate and reproducible results, measurements are ideally conducted in unfurnished units, as furniture and soft furnishings absorb sound and affect the reverberation conditions that influence measurement results. However, surveys can be conducted in furnished units with appropriate corrections applied. We discuss the specific conditions of each building during the initial consultation.

The technical report will clearly document the non-conformance, showing the measured values alongside the applicable regulatory thresholds. The report also includes a section on remediation options — describing the types of acoustic treatment that can improve performance for the specific transmission pathway that is deficient. This information can be used in conversations with the developer or for planning a remediation project.

Yes. Field measurements between occupied units are possible and are in fact the standard approach for existing buildings. The methodology accounts for background noise conditions and requires coordination between the occupants of the source and receiving units during the measurement session. We provide clear instructions for what is needed from each unit during the visit.

The Bixlume report is a technical document produced by a qualified professional using calibrated instruments and established measurement methodology. Its suitability for use in specific legal, administrative, or contractual contexts depends on the requirements of those proceedings. We recommend consulting with the relevant legal or administrative authority about the evidentiary requirements applicable to your specific situation.
