You spend hours poring over paint colors and fabric swatches. But an invisible and often-overlooked detail can vastly affect the enjoyment of your home – Sound.

With experience in diverse residential environments, Riedel works with home and condo owners, contractors, architects and interior designers to develop audio solutions for pre-construction and existing structures. We also provide noise abatement testing.

We can create the optimal listening environment for a home theater, optimize sound transmission in interior spaces, and quiet noise and vibration from outside sources—like traffic, airports, and railroads. Our services also include design of heating, ventilation, and air conditioning (HVAC), plumbing and other mechanical systems to keep the noise levels at a minimum.

Sound Transmission Testing
Professional Services & Fees

Scott R. Riedel & Associates, LTD. offers comprehensive sound transmission testing services to residences, business, and industrial clients nationwide. Our work for you will include onsite testing, data recording, and the development of a clear, readable report document. All field testing work will be performed according to the applicable national and international standards.

Airborne Noise Testing: Measures airborne sound transmission through wall or floor/ceiling assemblies. Shows existing sound insulation from sources including human voices, machinery, musical instruments, or stereo equipment. Airborne noise is rated in Field-STC (Sound Transmission Class) units.

Official Test Standards Followed: ISO 140-4 (ASTM E336-97), Airborne Noise Rating: ISO 717-1

Cost: $300 per partition

Impact Noise Testing: Measures structure-borne sound transmission through floor/ceiling assemblies. Shows existing sound insulation from footsteps or dog toenails in the unit above. Impact noise is rated in Field-IIC (Impact Isolation Class) units.

Official Test Standards Followed: ISO 140-7 (ASTM E1007-97), Impact Noise Rating: ISO 717-2

Cost: $300 per partition plus tapping machine rental fee.

The rental fee for a Bruel & Kjaer 3207 Tapping Machine, estimated to be about $600.00 plus approximately $75 shipping. These expenses will be billed at cost, with rental receipt documentation provided.

Scope of Work:
Each partition measured will include:

  1. Onsite measurement of wall or floor/ceiling partition noise control performance.
  2. Field testing procedures in accordance with ASTM standards and with appropriate equipment.
  3. Data recording.
  4. Comprehensive Field-IIC or Field-STC Report document for each tested partition.

Any travel expense related to your project will be mutually agreed upon in advance. Mileage is billed at current Federal Government allowance (currently $0.55 per mile), and any fares or tolls are billed at cost. Travel time is billed at a reduced rate of $35.00 per hour and is not figured into the above per-partition rate.

As we are not the representatives of any equipment supplier or acoustical material manufacturer, we are able to consult and advise in an objective manner with only the best interests of the client in mind.

Please feel free to call or email if you have any questions. We are here to help!

Condominium Noise Testing During Construction

During the construction process of a high-rise condominium building, sound transmission testing was performed to determine if the residential units would be adequately “sound separated” from neighboring units. Airborne sound (through walls and floors/ceilings) and structure borne sound (from footfall noise) was tested. Test data determined that requirements would be met and no remedial actions would be required.

Airport District Single Family Home Noise Testing and Recommendations

Governmental entities at one time offered either the installation of noise reducing features to single family homes or cash settlements for the value/cost of noise reduction to homeowners. The previous owner of this particular home accepted the cash settlement, but never had any noise reducing features installed. The new owner desired acoustical relief from airplane noise.

Testing was conducted over various day and night-time intervals to determine the ambient levels of unwanted airplane noise. From this data, recommendations were formulated to provide the homeowner with desired noise reduction. These included the installation of sound insulation and barrier materials, new insulated window and door units, and caulking and sealing of the house perimeters.

Occupied Condominium Noise Testing

In a large condominium development, some of the occupants have registered complaints about noise from adjoining neighbors while others with similar adjoining units have no complaints. Testing was desired to determine if all units had the same sound transmitting properties or if sound was transmitting differently at various locations in the development.

A testing protocol was developed to measure the same sound source intensity between various dwelling units. It was found that construction materials and methods, and therefore sound transmission, were indeed different at various locations in the development. Recommendations to reduce noise transmission at key locations were provided.
