Independent acoustic field testing for recording studios, production rooms, rehearsal spaces, control rooms and other critical-listening environments—before a site is selected, during construction, after completion, or when an existing space has an acoustic problem.
On-Site Acoustic Testing can document the existing acoustic environment, measure sound transmission to and from adjacent occupancies, evaluate room decay and absorptive treatment, and identify airborne or structure-borne paths that may affect recording, monitoring, or neighboring spaces.
Pre-Lease and Site-Selection Surveys
Before a studio is built, OSAT can survey a proposed location to establish the acoustic conditions that already exist. This can help identify problems that may be expensive or difficult to correct after a lease is signed or construction begins.
- Existing ambient and background noise levels
- Exterior noise intrusion from traffic, aircraft, rail, mechanical equipment, entertainment venues, or other sources
- Noise from adjacent tenants or neighboring buildings
- Structure-borne vibration or sound from equipment, building systems, elevators, fitness facilities, or other occupancies
- Representative daytime, nighttime, or operating-condition measurements where appropriate
Airborne and Structure-Borne Sound Transmission
Recording studios often need to control sound in both directions: preventing outside noise from entering critical spaces and limiting studio sound transmission to neighboring rooms, buildings, or occupancies. OSAT can measure transmission between adjacent spaces and between units above and below, and can investigate both airborne and structure-borne paths.
Where useful, testing can be coordinated with our building-acoustics testing services to evaluate walls, floors, ceilings, doors, glazing, penetrations, and other parts of the enclosure.
Room Reverberation and Decay Measurements
OSAT can measure reverberation time and frequency-dependent room decay to document how the space behaves acoustically. Measurements can be used to evaluate untreated rooms, completed studios, control rooms, live rooms, rehearsal spaces, vocal booths, or other critical-listening environments.
Frequency-specific results help show whether excessive decay is concentrated in particular bands rather than being distributed evenly across the spectrum.
Evaluating Absorptive Treatment
Where absorptive panels, ceiling treatments, wall systems, curtains, or other acoustic materials have been installed, OSAT can measure the room before and after treatment or compare treated and untreated conditions. This provides field evidence of whether the installed material is producing the intended reduction in reverberation and sound buildup.
Mechanical Noise and Vibration
HVAC systems, fans, pumps, electrical equipment, building services and nearby machinery can introduce tonal noise, low-frequency energy, vibration, or intermittent events that are especially noticeable in studios. OSAT can document these conditions and help determine whether the dominant path is airborne, structure-borne, or transmitted through ducts, penetrations, or building construction.
Troubleshooting Existing Studios
For studios that are already operating, testing can be used to investigate complaints such as excessive background noise, unexpected sound leakage, low-frequency transmission, mechanical noise, poor isolation between rooms, or acoustic treatment that is not performing as expected.
Where the source or path is difficult to isolate, OSAT can also use specialized source-localization methods including acoustic imaging and directional measurements.
What Clients Receive
Depending on the scope, deliverables can include measured ambient-noise levels, frequency spectra, airborne and structure-borne transmission results, reverberation-time data, measurement locations and operating conditions, photographs, comparison of treated and untreated conditions, identification of likely transmission paths or problem sources, and recommendations for additional investigation or corrective work.
Related Hospitality and Entertainment Spaces
Many of the same field-measurement methods apply to restaurants, bars, nightclubs and entertainment venues, where interior reverberation, amplified music, bass transmission, mechanical noise, neighboring occupancies and community noise may all need to be evaluated. See our Restaurant, Bar and Nightclub Noise Testing service.
