Measuring the Loudest Birds on Earth
Where in the wild have you taken your sound level meter? SoundAdvisor recently made a trip into the mountains of the Amazon rainforest at the northern edge of Brazil. Why? To try to capture the loudest bird call on earth.

It was a successful adventure with the White Bellbird recording 9 dB louder than its closest rival. SoundAdvisor offered the high temporal precision, wide frequency range, and synchronized sound recording to capture the necessary data.

Read the full account of the trek into the Amazon and check out a National Geographic article.
