How loud would the sun be measured on Earth if its soundwaves could propagate through space? The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun’s surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.
The constant flow of rising hot material to the surface and sinking of cooled material toward the center creates a cacophony estimated to be 10x to the 100x the power flux through speakers at a rock concert. Except the speaker, in this case, is the entire surface of the sun, some 10,000 times larger than the surface area of the Earth.

Exploring New Sounds with the World’s Largest Trees
What does one of the world’s largest lifeforms sound like? That was a question Ari Daniel asked on a recent National Public Radio (NPR) “All Things Considered” episode. Pando is a quaking aspen tree that has spread to cover over 80 football fields in Fishlake National Forest, Utah. While Pando may resemble a forest, what…
Mental Health, Quality of Life, and Communication in Children Diagnosed with Hearing Loss
Based on parent and teacher report, the prevalence of mental health problems is twice to four times higher in children diagnosed with hearing loss when compared to those peers without a hearing loss. Interestingly, children who are Deaf and hard-of-hearing (D/hh) and hard-of-hearing (HH) typically do not rate themselves as having significantly higher mental health…
