Question

A sound is measured to be 55 phons, how many sones is this equal to?

A) 1 sone
B) 2 sones
C) 4 sones
D) 8 sones

Answer 1

A sound measured at 55 phons is approximately equal to 1.375 sones.

Step-by-step explanation:

The loudness of a sound is measured in phons. To determine the number of sones equivalent to a given number of phons, we can use the formula:

1 sone = 40 phons

Therefore, if a sound is measured to be 55 phons, it is equal to:

(55 phons) / (40 phons/sone) = 1.375 sones

So, the answer is approximately 1.375 sones.

we cannot provide an exact answer to whether the correct response would be Option B) 2 sones or closer to the 3 sones mark. For exact conversions, one should use the appropriate psychometric function or conversion chart.
