We performed a noise study to define the existing sound within the neonatal unit and common areas of the Arnold Palmer Children's Hospital. We also determined the sound spectra of each piece of medical equipment used within the rooms. Our data was used to develop a sound absorption and masking system to make the area more acceptable to newborn babies and hospital staff.

Isolating noise areas from quiet areas is essential in many environments. In this example, Power Acoustics, Inc. performed noise tests within several video arcades to determine the sound pressure levels and spectrum shape expected inside the arcade. We then used the data to design wall and door systems with ample STC and sound transmission loss characteristics to contain the noise within the arcade and out of the hotel lobby.

Prior to renovations and remodeling, the members of this clubhouse believed the sound inside was acceptable during full capacity dining. After an architectural redesign, the visually appealing space was considered "loud" during events when the room was near maximum occupancy. It was found that during renovations much of the sound absorptive surfaces were removed. We measured the reverberation times within the space and developed an analytical acoustical model of the interior sound. Recommendations were made to help reduce the build-up of sound within the room with minimal impact to the visually appealing aesthetics of the renovation.

We've measured the sound from existing automotive centers, car washes and other retail stores as well as the current ambient sound levels near the residents affected by the proposed new facility. We used the sound level data collected to simulate the proposed facility's sound at the neighbor's homes and estimate its impact relative to the sound currently generated by roadways and other noise sources.

A new cooling tower exceeded a local property line noise ordinance. We designed noise abatement including sound walls and silencers to achieve the noise ordinance criteria and evaluated replacement cooling towers that would achieve the requirements.

A commercial kitchen was causing employee daily noise doses to exceed OSHA criteria for a hearing conservation program. We assessed the noise sources and designed noise abatement to help reduce sound within the facility.

Fitness Centers are difficult neighbors for adjoining office spaces. We assessed the noise transmission paths through floors, walls and ceilings and designed noise abatement to help reduce the transmission of vibration and sound to neighboring office areas.

Outdoor and Indoor racing facilities have unique noise problems. We've assessed the community noise impacts of outdoor facilities and the interior sound of Indoor facilities.

Each type of facility requires different types of noise abatement.

While outdoor facilities require assessment of sound barriers and estimating sound transmission to nearby neighbors, indoor facilities require building noise treatments to reduce noise heard by the drivers.

Power Acoustics, Inc. typical involvement as an expert witness is related to projects in need of special use permits or zoning approvals. However, we also perform work in eminent domain issues, criminal cases, and various other situations requiring acoustical expertise.
