Acoustic Envelope Detector

Measure sound, the fourth dimension of texture analysis.


Why measure sound?

  • Craft advertising language based on the sounds products make
  • Name products using onomatopoeia.
  • Utilize crispiness and crunchiness when consumers can’t taste or smell a product, like on TV.

Measurable Attributes

The ‘Crunch’ of brittle foods
The ‘Snap’ of a biscuit
The ‘Pop’ of a cork
The ‘Fizz’ of a bath bomb or Alka-Seltzer
The ‘Snap’ of a pencil
The ‘Click’ of a switch

Features

Acoustic data as rich as your product

  • Flawless discrimination between product sounds and instrument noise.
  • Generates synchronised force and sound profiles for individual tests.
  • Audio saved as .wav files for diagnostics and improved comprehension.
  • Audible range up to 12.5KHz.
  • Unit is individually matched to microphone sensitivity for better repeatability.

How It Works

How can you measure sound?

1

Make Noise

A microphone is connected to the TA.XTPlus and controlled by the Exponent software. The TA.XTPlus puts the sample under stress to get it to make noise.

2

Measure sound

Acoustic emission is measured (up to 12.5KHz). This emission is transformed into an analogue voltage to represent the amount of acoustic energy released from the product as a function of time.

3

Analyze data

Acoustic and force curves are viewed simultaneously, making the relationship between acoustic and force events easy to identify.
