CORPORATE PROJECT ACOUSTICAL ENGINEERING

PNC Bank Firstside Center, Pittsburgh, Pennsylvania

PNC Bank Firstside Center, Pittsburgh, Pennsylvania · Firstside Center is PNC Bank's state-of-the-art office and processing facility. 620,000 square feet are contained on five floors of this site along the Monogahela River in downtown Pittsburgh. Air conditioning for office areas is provided by an underfloor system.

Ostergaard Acoustical Associates provided consultation on the acoustics of training facilities, office areas, and HVAC system noise control. Issues included acoustical performance of finishes to control noise in open offices while achieving separation for closed offices. Ostergaard Acoustical Associates designed, specified, and tuned masking sound systems to serve all office areas.

Ingersoll Rand Business Development Center, Annandale, New Jersey · Although, as acoustical consultants, we advise on many projects with sound isolation challenges, this was a unique project. Ingersoll Rand planned to consolidate all life cycle and performance testing for a wide range of impact equipment, including jackhammers, into a test suite in the lower level of the new facility. This location is below office, museum, and lobby areas on the main floor. Ostergaard Acoustical Associates carried out sound and vibration measurements in Ingersoll Rand facilities in North Carolina, Pennsylvania, and New Jersey in preparation for our acoustical analyses to identify the types of construction needed to control the transfer of noise and vibration to assure adequate quiet in of the areas above.

Based on the measurements, anticipated sound levels in the test suite were in the 105-to-120 dB range. In order to isolate office areas from this noise, the intervening construction had to provide a hefty 60-to-75 dB of isolation. Heavy, double, room-within-a-room construction was required. This includes concrete plank ceilings with 24 inches clear beneath the 8-inch main level concrete slab. The plank is supported on concrete block walls that are free of the base building perimeter walls and columns. All ductwork for the test suite is located under the concrete plank and is distributed in a controlled way through central corridor. Because either a few large or many small impact devices are tested, the floors had to be vibration isolated from the building. The floor in each chamber is a freestanding 12-inch slab of concrete supported on steel springs on four foot centers that were selected to deflect 3-inches under the load of the slab.

Bell Atlantic Corporate Headquarters, Philadelphia, Pennsylvania · The corporate offices comprise 13 floors of the Bell Atlantic Tower including 11 floors of open and closed offices. The two top floors contain the corporate dining facility, the boardroom, a special conference room and the forum, a large hi-tech meeting space.

Acoustical features of the office floors include carefully selected acoustical finishes and wall construction selected to provide sound isolation between closed offices. A state-of-the-art electronic masking sound system designed and tuned by OAA to enhance privacy between open and closed offices and assure reduced distraction for office personnel.

Three major meeting spaces are on floors 50 and 51. These uppermost floors are double height and have panoramic views of the city. Since unassisted voice communication is important for such spaces, OAA provided guidance to assure good natural voice acoustics. Measures included finishes for reverberation control, and special sound isolating constructions to assure that noise from adjacent mechanical rooms does not interfere. A combination of on site inspections and measurement, thorough acoustical analysis and experience made this possible.

Verizon Wireless Network Facility, Southlake, Texas · OAA provided consultation on a wide range of issues in order to meet the acoustical needs of this 175,000 sq. ft. facility.

  • Network Operation Center – Finishes to control activity noise that are architecturally compatible.
  • Closed Offices – Methods to achieve needed acoustical separation.
  • Special Conference Rooms – Guidance on controlling interior acoustics for clarity, natural speech reinforcement, and teleconferencing without acoustical problems.
  • Open Office – Specified ceiling performance for quieting, including telemarketing areas.
  • Noise Code Compliance – Evaluated alternate methods for controlling the noise of a wide range of large exterior equipment, including get-sets and cooling towers, in order to meet local code.

Masking Sound Systems

Use of electronically-generated masking sound has become a universally accepted tool to improve speech privacy and promote quiet in office areas. This concept was introduced and has been refined by Ostergaard Acoustical Associates personnel over the past three decades. Custom masking sound systems are engineered and tuned by Ostergaard Acoustical Associates to achieve maximum masking effect with minimal awareness by office personnel. This is because our systems provide uniformity, as well as optimum level and spectrum shape. Our systems automatically reduce masking levels after hours, and can accommodate announce capability. The following clients have benefited from masking system installations engineered and tuned by Ostergaard Acoustical Associates. Our clients include:
