Why Are Siamangs Considered the Loudest Primates?

💡 The Answer

• Siamangs produce calls that can reach 100 decibels, rivaling a rock concert.
• The inflatable throat sac acts as a resonance chamber to amplify sound.
• Their calls serve to advertise territory size and location to neighbors.
• The low-frequency components of their calls travel well through dense foliage.
