Empathy02:34

Empathy

9.8K
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Perception of Sound Waves01:01

Perception of Sound Waves

4.8K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

Labeling Emotion01:20

Labeling Emotion

364
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Auditory Perception01:17

Auditory Perception

656
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Area of Science:

  • * Music and Emotion Analysis
  • * Affective Computing
  • * Advertising Technology

Background:

  • * Online video consumption is prevalent, with music significantly influencing viewer emotions and perceptions.
  • * Understanding the link between music's physical properties and empathy is crucial for effective advertising.
  • * Previous research has not fully explored specific audio features that elicit empathy.

Purpose of the Study:

  • * To analyze music features in advertising videos that induce empathy.
  • * To identify specific audio characteristics correlating with emotional resonance.
  • * To develop a real-time advertisement empathy monitoring system.

Main Methods:

  • * Combined Mel-frequency cepstral coefficients (MFCC) power spectrum analysis with image RGB analysis.
  • * Utilized spectral analysis to categorize eigenvectors from low (blue) to high (red) frequencies.
  • * Employed a random forest classifier for data classification and model training.

Main Results:

  • * Achieved high accuracy with a trained model: 99.173% training accuracy and 86.171% test accuracy.
  • * Identified low-frequency, high-amplitude audio as more empathetic than high-frequency, high-amplitude audio.
  • * Determined frequency and audio amplitude as critical waveform attributes.

Conclusions:

  • * Spectrogram image features of audio offer the most potent method for inducing human empathy.
  • * The developed method provides a novel approach to audio extraction for empathy induction.
  • * Findings are valuable for advertisers seeking to enhance emotional connection with audiences.
