What decibel loss can occur due to a closed door between a sounder and a mattress?

The range of 10 to 24 decibels is associated with sound attenuation caused by obstacles like a closed door between a sound source (the sounder) and a receiver (the mattress). This level of reduction is noteworthy as it indicates how sound pressure levels can be significantly diminished when encountering barriers.

In practical terms, the materials used in constructing the door, as well as any gaps and how well the door seals, can impact sound transmission. Therefore, the sound intensity can drop within this range when the sound waves need to penetrate through materials that reflect and absorb some of that sound energy.

This attenuation highlights the importance of considering environmental factors in sound design and alarm systems, as it affects the effectiveness of audible alerts in situations where barriers are present.
