Sound Level Sensor

This Sound Level Sensor enables students to measure sound intensity in decibels (dBA) or waveform (mV), closely approximating human hearing range and sensitivity. It's ideal for physics experiments and real-world applications such as environmental monitoring or sound insulation studies.

Educational Benefits

• Introduces sound wave properties and acoustics.
• Encourages exploration of sound intensity and frequency.
• Promotes critical thinking through real-world data collection.
• Links theoretical learning with practical sensor use.

Classroom Applications

• Measure sound decay over distance.
• Compare insulation effectiveness in different materials.
• Analyse amplitude and frequency using waveforms.
• Investigate speed of sound in solids and air with two sensors.

Specifications

• Measurement modes: dBA and waveform (mV)
• Dual range: Human-ear sensitivity emulation
• Application: Physics, sound insulation, environmental science
• Suitable for: Upper primary to senior secondary
