Dayton T. Brown, Inc. Extends Acoustic Capabilities with Siemens Digital Industries Software

DFAN Testing at Dayton T. Brown, Inc.

BOHEMIA, NY, UNITED STATES, December 19, 2022 /EINPresswire.com/ --
• Direct Field Acoustic Noise testing as a service performed with Siemens’ Simcenter Engineering Services team
• Complete test campaigns executed in one location
• Increase accuracy by utilizing both simulation and test

Dayton T. Brown, Inc. (DTB) and Siemens Digital Industries Software have collaborated to offer Direct Field Acoustic Noise Testing (DFAN) as a

service to the aerospace, military, and space industries. This cooperation leverages DTB’s vibration and acoustic expertise with Siemens’ Simcenter™ SCADAS™ hardware and Simcenter™ Testlab™ products and engineering services from Siemens’ Simcenter Engineering Services team. Together DTB and Siemens are now delivering acoustics, vibration, shock, and DFAN in one location to better serve the aerospace and defense industry.

Direct Field Acoustic Noise Testing, also known as DFAN, is today an accepted industry method to replicate the vibro-acoustic conditions a spacecraft and individual components will experience at launch. Simulation of the environment is achieved with an optimized speaker system and the industry recognized Simcenter Testlab Multiple-Input Multiple-Output Random Control for DFAN solution. DFAN provides aerospace, military, and space companies and suppliers with an alternative to the traditional reverberant field acoustic testing. This technology does not require a dedicated facility and test can be conducted at the customer’s site if necessary. This reduces the handling risk during transportation, as well as the potential risk of program cost and schedule overruns.
