1.	By directing the exhaust away from the ground we can _____________(a) reduce the aural signature(b) increase the aural signature(c) increase noise(d) noise is not dependent on the direction of exhaustThe question was asked in an interview for job.My question is taken from Configuration Layout Considerations topic in division Configuration Layout Considerations of Aircraft Design
Answer» The CORRECT option is (a) reduce the AURAL signature The EXPLANATION: By redirecting exhaust stacks away from the GROUND we can reduce the aural signature. We can reduce aural signatures by using MUFFLERS or by providing proper insulation as well.
