Effects of feedback

Effects of feedback

Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Problem-Solving: Tuning of a Guitar String

Problem-Solving: Tuning of a Guitar String

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...

Feedback Loops

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.

Passive Filters

Passive Filters

Passive filters are utilized to shape the frequency spectrum of signals across a diverse array of applications. These filters, using only passive elements like resistors (R), inductors (L), and capacitors (C), are capable of selectively allowing or blocking certain frequency ranges without the need for external power sources.
Low-Pass Filters
Low-pass filters are designed to transmit signals with frequencies lower than the cutoff frequency, ωc, and attenuate those above it. The cutoff...

Feedback Inhibition

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Anatomy of the Ear

Anatomy of the Ear

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...

Area of Science:

Vocal acoustics
Singing voice science

Background:

The male secondo passaggio involves specific vocal adjustments for classical singing.
Understanding these adjustments is key to producing the desired male upper voice timbre.

Purpose of the Study:

Investigate singer choices during passaggio negotiation.
Examine vocal tract feedback to the voice source during this maneuver.

Main Methods:

Recorded electroglottograph (EGG) and microphone signals from nine male singers.
Utilized VoceVista software for data acquisition.
Performed inverse filtering on microphone signals using Sopran/DeCap to analyze glottal airflow pulses.

Main Results:

Identified two key adjustments for the male secondo passaggio: H2 passing F1 and altered vocal timbre.
Observed optimal arrangements involving F2 tuning or singer's formant cluster resonance (2.4-3.4 kHz).
Revealed individual singer variations in managing the passaggio.

Conclusions:

The male secondo passaggio is achieved through specific harmonic and formant adjustments.
Vocal tract feedback plays a role in voice source modulation during passaggio.
These findings contribute to understanding the production of the classical male upper voice.
