Final answer:

Statement One is correct as sound can travel through air and structures, which both need to be accounted for in noise management. Statement Two is also correct; sound absorbers reduce energy from sound waves, whereas insulators prevent sound transmission between spaces. Therefore, the statements are correct and linked to each other.

Step-by-step explanation:

When examining the statements given, Statement One is correct as sound can travel in both air and through structures. This is relevant because sound will behave differently depending on the medium through which it moves, and different materials will have an impact on the propagation of sound. For instance, sound travels faster in solids than in gases because particles are closer together. Considering both air and structure-borne sound is important when tackling noise reduction in the workplace.

Statement Two is also correct, but requires a clarification: sound absorbers and sound insulators serve different purposes. Absorbers reduce the energy of sound waves within a space, thus reducing reverberation and echo, while insulators prevent the transmission of sound from one area to another. Both techniques are important in noise reduction strategies, but they are not interchangeable. The performance of an absorber or insulator depends on factors such as material density, texture, and installation.

The most appropriate answer is (c) Statement one is correct and is linked to statement two. This is because the effectiveness of noise reduction measures relies on understanding both how sound travels and the application of the correct type of sound-modifying materials.
