Design Example: Vintage Mixing Console

203
A sound engineer at a music company recently encountered a problem. The output from their newly acquired studio's vintage mixing console was too low for the requirements of modern recording equipment. To rectify this situation, the engineer decided to design an audio pre-amplifier using an operational amplifier (op-amp) to boost the signal level.
The specifications for the pre-amplifier were clear. It needed to amplify the audio signal by a factor of 10, have an input impedance above 10...

Anatomy of the Ear01:16

Anatomy of the Ear

7.2K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Feedback Loops01:01

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Hearing

51.8K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Problem-Solving: Tuning of a Guitar String

401
In the case of stringed instruments like the guitar, the elastic property that determines the speed of the sound produced is its linear mass density or the mass per unit length. This is simply called the linear density. If the string's linear density is constant along the string, then the linear density is simply the total mass divided by the total length.
The string's wave speed can be regulated by varying the linear density. Tension is the other property that determines the speed of...

The Cochlea01:13

The Cochlea

44.5K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Summary
This summary is machine-generated.

A hearing loop did not significantly improve sound quality for hearing aid users at an orchestral concert. The "no feed" condition performed best, suggesting current assistive listening systems may not be optimal for live orchestral music.

Area of Science:

  • Audiology and Hearing Science
  • Music Acoustics
  • Gerontology

Background:

  • Live music enhances social connectedness in older adults, combating isolation linked to hearing loss and aging.
  • Hearing aid (HA) users often report dissatisfaction with live music sound quality, impacting their engagement.
  • Existing assistive listening systems may not adequately address individual hearing loss needs or integrate with HAs.

Purpose of the Study:

  • To evaluate the effectiveness of a hearing loop system in improving the perceived sound quality of live orchestral music for HA users.
  • To compare sound quality and naturalness ratings across different hearing loop input conditions.

Main Methods:

  • Participants with moderate-to-severe hearing loss used either Sonova HAs with telecoils or their own HAs without telecoils.
  • A hearing loop system was tested with three input conditions: hall's standard assistive feed (house), stage microphones (stage), and no input (no feed).
  • Sound quality and naturalness were rated after each 5-minute interval across different loop conditions during an orchestral concert.

Main Results:

  • Sound quality and naturalness ratings were highly correlated (rRM = 0.81).
  • The 'no feed' condition significantly outperformed the 'house' condition for both sound quality and naturalness (adj. p < 0.01).
  • While mixed-effects models provided insights, assumption violations limited further interpretation of the data.

Conclusions:

  • Hearing loop systems may not be essential for enhancing the experience of orchestral music for hearing aid users.
  • Further research is needed to improve lyric intelligibility and personalize user experiences, potentially through emerging technologies like Bluetooth Low Energy Audio.
