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

55.7K
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

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.

听力循环在乐团音乐会上对助听器使用者来说并没有显著改善声音质量. "无源"条件表现最好,这表明当前的辅助听力系统可能不适合现场管弦乐音乐.

科学领域:

  • 听力学和听力科学 听力学和听力科学
  • 音乐声学 音乐的声学
  • 老年学是一门学科.

背景情况:

  • 现场音乐增强了老年人的社会联系,打击与听力损失和衰老相关的孤立.
  • 助听器 (HA) 用户经常报告对现场音乐声音质量不满,这影响了他们的参与度.
  • 现有的助听系统可能无法充分满足个体听力损失的需求或与HA集成.

研究的目的:

  • 评估一个听力循环系统在改善 HA 用户感知现场乐队音乐的声音质量的有效性.
  • 为了在不同的听力环输入条件中比较声音质量和自然度等级.

主要方法:

  • 患有中度至重度听力损失的参与者使用了带有电线圈的Sonova HA或没有电线圈的他们自己的HA.
  • 一个听力循环系统在三个输入条件下进行了测试:大厅的标准辅助输入 (房子),舞台麦克风 (舞台) 和没有输入 (没有输入).
  • 在乐队音乐会期间,在不同的循环条件下,在每5分钟间隔后对声音质量和自然度进行了评分.

主要成果:

  • 声音质量和自然度的评分高度相关 (rRM = 0.81).
  • "没有料"条件在声音质量和自然性 (adj. p<0.01) 的情况.
  • 虽然混合效应模型提供了洞察力,但假设违反限制了进一步解释数据.

结论:

  • 听力循环系统对于提高助听器使用者的管弦乐音乐体验可能并不必不可少.
  • 需要进一步的研究来提高歌词的可理解性和个性化用户体验,可能是通过新兴技术,如蓝牙低能耗音频.
