Cue 16 Reflections

Ok, I'm going to attempt to finish my reflections from the CUE 16 Palm Springs Convention. This is not easy you see because, I've been stalling since there was just so much that happened. I'm actually trying to use the voice typing feature in Google Docs to help me so please forgive me if a little this is pretty disjointed.

The Church came into being when Christ died on the Cross, and it was formally inaugurated at Pentecost when he sent the Holy Spirit as he had promised. This reflection takes its cue from today's Gospel in a reference to the Holy Spirit:

Do not worry about how you are to speak or what you are to say. You
will be given at that moment what you are to say. For it will not be you
who speak but the Spirit of your Father speaking through you. (Mt 10: 16-23)

The Holy Spirit speaks through us, just as he spoke through Christ when he delivered his Sermon on the Mount, confronted the Pharisees, and told his parables. Mega manfree flash games. Fear never seems to characterize his disposition in circumstances calling for him to speak.

Christ certainly experienced fear as he anticipated the cross. No doubt he had fear when, from the cross and in the duress of ultimate spiritual dryness, he said 'I thirst' and quoted from Psalm 22, 'My God, My God, why have you abandoned me?' But his response to that fear was pure trust: 'Into your hands I commend my spirit.' Nor did he have worries about saying the right thing when he spoke of his executioners from the cross, 'Father, forgive them: they do not know what they are doing.'

Why was that? Since he wanted simply and solely to do his Father's will, he knew that in speaking he would be guided by the Holy Spirit. In situations where Christ spoke to others his driving motive, as in everything, was to do his Father's will. Because of that he was acutely sensitive to the Father's will. He trusted that what he wanted to say was the right thing in the moment and was emboldened by the Holy Spirit prompting him to deliver his words. He had the holy instinct that as he spoke he was doing what the Father wanted because his entire objective was that his Father's will be done. He therefore trusted that whatever he did or said was the right thing in the particulars of the moment.

So too with us. We often are in situations calling us to speak for the glory of God, whether the circumstances demand that we confront forces of evil with our words, express our compassion to those who suffer, or respond to others in any moment moving us to bear witness to the love and wisdom of God. In such situations, as was the case with Christ in his public ministry, our grace is to be sensitive to the will of God, rely on the guidance of the Holy Spirit, and then speak out as best we can to address the situation. We will deliver our words with no worries when they reflect our holy instincts that what we want to say is, God willing, the right thing to say. That's all we can do. That is the way we try to do God's will, and it is precisely our trying to do so that God wants from us. In other words, that is his will for us in the moment. We often are in circumstances where we cannot plan what to say, but must speak the truth, words of compassion, or bare witness as best we can. We trust that the Holy Spirit will speak through us and accomplish what God wants accomplished.

The reason why this is the Christian way of proceeding is that, in the strength of our Faith and the grace of our Baptism, we are in fact joined to Christ – whatever the situation. We are his Mystical Body and are fed at his Eucharistic feast. In, with, and through Christ, we will always want what God wants. To the extent our driving motive is to do God's will, it is precisely in these situations that we, as promised, will be guided by the Holy Spirit. And in that disposition, we will respond to the Lord's comforting demand, 'Do not worry . . . For it will not be you who speak but the Spirit of your Father speaking through you.'

Pinna reflections

Batteau first proposed the localization theory based onpinna reflections. Batteau suggested that the structure of the pinna causedmultiple reflections of sound and the delay betwee the direct and the reflectedsound varies with the direction of the sound source.

[ batteau-1967 ] D. W. Batteau, The Role of the Pinna in Human Localization Proceedings of the Royal Society of London. Series B, Biological Sciences, Vol. 168, No. 1011. (Aug. 15, 1967), pp. 158-180.

'The role of the pinna in localization is tointroduce, by means of delay paths, a transformation of the incoming signalwhich is mentally inverted to provide attention, and that the inverse transformrequired defines the localization of the sound source.'

One of the earliest papers to give model for the pinna in terms of multiple reflections. There are multiple paths sound should travel before reaching the pinna. Because of the different path-length s there are multiple delays involved. The delays inroduced by the pinna were easliy seen to depend on the orientation of the sound source with respect to the pinna.

Hebrank and wright argue that the pinna notch isdomiant cue for localization in the median vertical plane. The case of the pinnaspectral notches is attributed to the reflection of the sound from the posteriorconcha wall.

[ wright_jasa1974 ] Wright D, Hebrank JH, and Wilson B. Pinna reflections as cues for localization. J Acoust Soc Am 56: 957-962, 1974.

This paper presents experiments to determine whetherdelays caused due to pinna reflections are detectable by humans. The resultsshow that delay times of of 20 usec are easily recognizable when the amplituderatio of the dealyed delayed signal to the leading signal is greater than0.67. Just noticeable results agreed with the measurements of the minimumaudible angle for monaural localization.

[ hebrank_jasa1974b ] Hebrank, J., Wright, D., Spectral Cues Used in the Location of Sound Sources on the Median Plane, Pages 1829 - 1834, J. Acoust. Soc. Amer., 56(6), 1974.

Sound spectra from 4 to 16 khz are necessary forlocalization. Specifically identified three cues by experiments. Frontal cuesare a 1-octave notch betwee 4 to 10 kHz, above cue is a one-octave peak between7-9 khz and behind cue is a peak between 10 to 12 kHz. Increases in frontalelevation are signalled by the increase in the lower cutoff frequency of the1-octave notch. The notch appears to be generated by time-dealyed reflectionsoff the posterior concha wall interfering with sound directly entering theexternal auditory canal. Alsp speculate that the association between auditoryand spatial highness results from the frontal elevation cue.

This idea was further refined by Lopez Poveda whoincorporated diffractionin the model and the predicted spectral notches agreedclosely with the measured ones.

This paper proposes a physical model for the human concha based on diffraction and reflection. The sound wave is scattered within the concha cavity and therefore significant reflections must occur on an infinite number of points along the posterior wall for all source locations. The model predicts the elevation-dependent spectral features related to the transverse dimensions of the concha. Specifially nulls N1 and N3 agreed with their prediction. However the null N2 did not show up. This could be due to the crus helias. One thing to be noted from this paper is that a simple dealy model may not accrately predict the location of the nulls (due to diffraction). Can explain the notches in the contrlateral side if we assume that the sound creeps around the head entering the contralateral concha at approximately the same elevation angle as if the source was in the ipsilateral hemisphere
